Secrets of the SimXperience AccuForce Pro

Welcome to Secrets of the SimXperience AccuForce Pro where I will be recording my experience, tips, tricks, resources, and other helpful information as I get to know it.

Secrets is a series of blog posts I started with Secrets of iRacing and which has grown to include Secrets of GTR2, Secrets of Race 07, Secrets of GT Legends, Secrets of Automobilista, Secrets of rFactor 2, and Secrets of the SimXperience AccuForce Pro. The “secrets” part is a little dramatic but there are quite a few tips and tricks I think new users will find very valuable and interesting.

Update 2019-05-21: Updated Assetto Corsa > Force Feedback Settings. Able to get some Filter road feel back with further tuning.

Update 2019-05-20: Added Assetto Corsa > Force Feedback Settings. I’ve finally found informative, clean, smooth ffb, after all this time, after deciding to deep dive into AC FFB tuning.

Update 2019-05-03: Added Project Cars 2 > Unexpected/Unnatural Rotation/Oversteer In Corners on Throttle Lift-off

Update 2019-02-23: Updated FFB settings for Improved FFB with Jack Spade Custom FFB Files: Particularly tuning Test 8.3 for improved oversteer catch/overweight steering feeling in hard cornering.

Update 2019-02-22: Updated FFB settings for Improved FFB with Jack Spade Custom FFB Files: Particularly tuning Test 8.2 for improved over-weighty/soft-clipping feeling.

Update 2019-01-26: Updated FFB settings for Improved FFB with Jack Spade Custom FFB Files:Particularly tuning Test 8.1 for improving ability to catch oversteer, improve wheel weight in corners, try out more FX.

Update 2018-10-12: Updated FFB settings for Improved FFB with Jack Spade Custom FFB Files.

Update 2018-09-28: Initial publication

What is the SimXperience AccuForce Pro?

The AccuForce Pro is a force feedback steering wheel system used mainly for sim racing on PC

From the SimXperience website,

The AccuForce Pro V2 Steering System Kit is a complete Plug-N-Play package of our most advanced and realistic direct drive force feedback system. With unparalleled realism and the most advanced tuning features on the market, the AccuForce Pro not only delivers significant advantages for hardcore sim racers but is an effective training tool for real world drivers as well.

Here’s a taste of what it is and how it plays in games, from Inside Sim Racing and their short review,

Getting Started

In Secrets, I try to focus on the non-obvious or unintuitive so I won’t be covering basics like getting the wheel or installing it, unless there is is something of note to comment onm. You’re probably beyond that yourself so I’ll focus on the more obscure and non-obvious things.

How much FFB can you feel in GTR2? 1/1000th of a percent.

[This is a repost of a thread I started on RaceDepartment.com and just wanted to have on my blog, as well.]

Update 2018-01-25: I’m a fan of Simracing Youtuber Jimmy Broadbent and he recently noticed my RaceDepartment post How much FFB can you feel in GTR2? 1/1000 of a percent (also a blog post of mine) and posted a video about his direct drive experience on GTR2 using the force feedback settings I recommended in that post: GTR 2 – How Does It Feel With A Direct Drive Wheel? Check it out, he seems to like it! I’m really happy to help some people get more enjoyment out of this oldie-but-goodie game.

I thought the GTR2 fans would find these results on the precision of GTR2 FFB interesting. For the record, I run a SimXperience Accuforce direct drive wheel. Precision probably wouldn’t be as noticeable on belt/gear wheels.

I’ve been tuning force feedback and recording details on my blog and, in any game where I need to tune value ranges, I find myself doing bi-section searches and testing the result to find what suits me best for a particular FFB parameter.

Here’s my latest testing on this parameter in the UserData PLR file:

FFB steer force grip weight=”0.71696″ // Range 0.0 to 1.0, recommended: 0.4 to 0.9. How much weight is given to tire grip when calculating steering force.

Note 0.71696 is basically 71.696% given the 0.0-1.0 range. GTR2’s PLR files apparently have a precision of up to 5 decimal places or 1/1000th precision thought of as a percentage.

How did I end up at a super specific value like that? Well, here’s the bi-section search it took me to arrive at that value:

FFB steer force grip weight=”0.78000″, 0.785, 0.7875, 0.6875, 0.7875, 0.6875, 0.7375, 0.7125, 0.725, 0.71875, 0.715625, 0.7171875 (better), 0.71640625, 0.716796875, 0.7169921875, 0.71689453125, 0.716943359375, (0.7169189453125+ vs 0.7169677734375++), 0.71695556640625 (*, **, ***)

Yes, at every step I could tell the difference (note the “better” notation, and the “+” and “++” notations). I was choosing what gave me a better feeling of grip level while cornering.

Those last two values were (when rounded) really 71.697% and 71.696%: A 1/1000th precision difference that you could feel in the wheel.

Some might be skeptical, I understand, just be aware this is really only perceptible when you’re going hard like say for fastest lap in a qualifying session. Precision of ffb matters at that point.

Personally, I find it really fascinating to push an old game like GTR2 from 2006 this far and find out it can deliver that kind of fidelity on a modern direct drive wheel.

*Yes, to update those values I have to exit GTR2, edit the PLR, and start GTR2 back up again. A real pain but worth it when you start to feel the car as it was meant to be felt.

**My “bi-section searching” deviates from a strict bi-section search in that sometimes I experiment and try values that aren’t strictly a bi-section the previous two values. I find this can help when I’m frustrated with the feel and need to find my bearings with a bigger jump which I then narrow down again with a regular bi-section search.

***If you’re interested, I’ve attached my PLR so you can see all my modified FFB values. The car was HQ F575 GTC and the track was HQ Brno. I run 60hz vsync.

Secrets of GTR2

Welcome to Secrets of GTR2 where I will be recording my experience, tips, tricks, resources and other helpful information as I get into GTR2.

Secrets of GTR2

Welcome to Secrets of GTR2 where I will be recording my experience, tips, tricks, resources and other helpful information as I get into GTR2.

Secrets of is a series of blog posts I started with Secrets of iRacing and which has grown to include Secrets of GTR2, Secrets of Race 07, Secrets of Automobilista, and Secrets of rFactor 2. The “secrets” part is a little dramatic but there are quite a few tips and tricks I think new users will find very valuable and interesting.

Update 2019-02-26: MRW Cars: If the cars feel like they’re not turning enough for how much you turn your wheel, trying increasing the Wheel Lock in-game. The default is something like 15deg but I’ve tried 18, 21, 24, and I’m now at 25 and that feels about right. It seems high but I guess pickers can’t be choosers.

Update 2019-02-25 – 3: I’ve recently joined the F1 Classic Forums and I can totally recommend this site as another quality place for getting involved in the GTR2 community.

Update 2019-02-25 – 2: Here’s an XD overlay tweak to the XD.INI file that repositions the Standings Box to top-left, to the right of the native Position dialog. This prevents the Standings Box from getting in the way of the rearview mirror. Here’s the tweak:  StandingsPosX=370 and StandingsPosY=0. To reduce the number of entries in the Standings Box, so it takes up less space, set StandingsPlayersVisible=7. I find this improves the layout and frees up the screen for where you really want to look while you’re racing. Added this info under Modernizing > XD Telemetry Overlay.

Update 2019-02-25: After talking with the MRW Cars author, it appears he set HDC files SteeringFFBMult=3.0 (Default: 1.2) which is why I had to drastically change FFB Steer Force Output Max (See Update 2019-02-21 for details). So, now, instead of modifying Steer Force Output Max away from the previous value, and breaking the FFB experience for every other mod since the previous value worked relatively well across mods, you can use the previous FFB steer force output max=”0.95000″ and, instead, change the MRW Cars HDC files SteeringFFBMult=1.2 to match every other mod. This results in a much better feeling while retaining compatibility across other mods.

Update 2019-02-21 – 2: Cleaned out the Mod Bounty Program. It never really got going and it doesn’t seem to mesh with the mod culture of these old games. That’s actually okay. Modders have integrity and honour and do this on their own time, for free, because of their passion. I can respect that. Thank you, modders!

Update 2019-02-21: I’ve currently tuning FFB for the amazing MRW Car sets (Cup, GT4, GT3 and GT3) and have promising results. For now, set FFB steer force output max=”0.53438″ and that should mostly do it. I feel like I will have to tune Grip Weight but don’t have any numbers for that yet. That said, it still fees very good so far. You can find all the details about how to get the MRW Car Sets on the EEC Forums. You’ll need to register with them but their mods are worth it! I’ll be reviewing the MRW Cars in the Mod Spotlight soon.

Update 2019-02-18: GTR233 and Co. have released both of the amazing GTR2 HQ Mods Collection v9.7 and GTR2 10th Anniversary Patch v9.7 mods! These are absolute must-haves for GTR2 fans. The 10th Anniversary Patch is one of the best and simplest ways to take a vanilla GTR2 install and modernize it all in one easy step. You won’t be disappointed!

Update 2019-02-03: Added Power & Glory 3 to the Table of Mods and Custom FFB Files.

Update 2018-10-14: TrackIR users probably want to set Video options World Movement to 1% (not zero) to stabilize the vertical angle of the cockpit camera to the angle of the car so that when you’re going up or down a steep hill you don’t lose sight of the bonnet of your car looking too far up while going downhill or end up looking at your feet looking too far down going uphill. Zero World Movement is lock-to-horizon, I guess, and to me that doesn’t work for TrackIR users. World Movement greater than 1% causes your cockpit camera to stabilize with the car angle but the “world” (ie. what you see of the car and the track) ends up bouncing around so a high World Movement number isn’t great, either. So 1% seems to minimize ‘world shake’ and stabilize the cockpit camera to help when you’re going up and down hills. Added tip here.

Update 2018-09-28: Certified new HQ Cars with significant grip increase changes. No more of the wheel going super light. The downside is non-direct drive wheels might not convey the grip information that is still there as well as before. A Pre-2018-09-28 download is still available if you don’t like it.

Update 2018-09-28 – 2: Added DTM 2012-2016 Mod to Table of Mods and Custom FFB Files.

Update 2018-09-09: I’ve been working on a significant update to the HQ Cars FFB settings (which should benefit other car sets in the future) involving tuning the ‘light wheel during grip loss’ effect for more realistic behaviour and I’m very pleased with my results so far. In some cases it can feel rFactor2-like(!) such as when regaining grip when going light over high-speed ridges. I even posted about a particular finding over at Race Department with respect to actually feeling very specific front-left whee lockup on heavy braking into left-hand corners (same would apply to right-hand corners, of course). Give this PLR a try if you’re interested. Just copy&paste the FFB lines into your own PLR. Make a backup of your own, of course! :) When I’m satisfied with tuning I’ll update the official HQ Cars FFB settings. Enjoy!

Update 2018-09-02 (2): Added the free Bill’s Process Manager as the primary recommendation for the section Improve Frame Rate by Making GTR2 Use More Cores For Better Performance.

Update 2018-09-02: Check out my new Secrets of Race 07 post –  I’ve recently got back into Race 07 after watching a recent Race Department video and discovering that my GTR2 FFB settings worked really well in Race 07. Beware SimXperience AccuForce owners: Disable Dynamic Oscillation Control – Stationary or the FFB will feel incredibly dull and extremely over-dampened.

Update 2018-08-28: Correction to Field of View instructions. ProjectImmersion.com’s vFOV value is used as-is not a calculation against default value.

Update 2018-06-13: Fixed PLR link for FFB settings for Original Cars under Force Feedback > Shovas Custom FFB Files.

2018-06-08 – 3: Updated Mod Spotlight > EEC GT3 V3 with some potentially helpful notes on how to get started installing it.

Update 2018-06-08 – 2: Added my NVIDIA Inspector customization notes for improved graphics under Getting Started > Modernizing > NVIDIA Inspector Settings.

Update 2018-06-08: I’ve now certified my new FFB settings for DTM Classics cars which are now rebased on the benchmark 2005 FiaGT Mod FFB settings. Check out Force Feedback > Shovas Custom FFB Files for the PLR download.

Update 2018-06-04: There’s an update over on my NoGripRacing.com Is Down post. Check it out for the latest on what happened to NoGripRacing.com and details on how we might be able to help recover the site! PS. There are full backups! Catch? Sounds like unpaid bills to pay before they’re released :(

Update 2018-06-03: I’ve now certified my new FFB settings for HQ Cars which are now rebased on the benchmark 2005 FiaGT Mod FFB settings. Check out Force Feedback > Shovas Custom FFB Files for the PLR download.

Update 2018-05-30: NoGripRacing.com has been down for most of today. Anyone have any news? It would be a crying shame if it were permanently lost – there were so many downloads there and lots of good people. I would be happy to provide some kind of mirror hosting if anybody knows how to get in contact with the owner.

Update 2018-05-25: I’ve now certified my FFB settings for Original Cars. Check out Force Feedback > Shovas Custom FFB Files for the PLR download.

Update 2018-05-21 – 2: I have now certified my FFB PLR for the FiaGT 2005 Mod. Check out Force Feedback > Shovas Custom FFB Files for the PLR download. In my opinion, FiaGT 2005 is currently the best mod available. It doesn’t try to do too much, just provide the FIA GT 2005 season, and that’s how it keeps everything tight and polished and feeling high quality. Give it a try if you haven’t already, it’s well worth it!

Update 2018-05-21: Updated Force Feedback > Shovas Custom FFB Files for FiaGT 2005 Mod. This is now my best feeling FFB + Mod set.

Update 2018-05-13: Added David Littman’s mod bounty to the GTR2 Mod Bounty Program.

Update 2018-03-25: Introducing the GTR2 Mod Bounty Program: A system to match pledgers with modders to improve the game we all love, GTR2. Take a look at the available bounties and consider pledging to see if we can gather some interest in keeping GTR2 alive and kicking!

Update 2018-03-24: Updated Force Feedback > The GTR2 Force Feedback Engineer with advice for FFB adjustments when your wheel goes numb, like it’s clipping, even though you’re not at max FFB strength.

Update 2018-03-23: Correction on Troubleshooting > Graphics driver crash and black screen freeze while driving: This problem seems to have been due to bad files in my GTR2 folder. I started again with a clean, brand new GTR2 installation, and tested with crash-prone cars and tracks and haven’t had a black screen freeze crash again, yet *fingerscrossed*.

Update 2018-03-05: Updated Mod Spotlight > DTM Classics Mod to (1) recommend NOT raising Max Vehicles on tracks to avoid some pit issues, and (2) provided a ‘plain’ championship that allows for custom race durations (in minutes) and avoids repeating tracks. Added Troubleshooting > Graphics driver crash and black screen freeze while driving.

Update 2018-02-16 – 3: Updated Force Feedback > Shovas Custom FFB Files for WSGT Mod cars but unfortunately, due to consistency issues with the cars physics and handling in the mod, FFB could be tuned for one car but not for all. You’d have to tune each car separately which I’m not willing to put the effort into. There are also tire heating/cooling problems with the mod. Sadly, will have to avoid this mod for now.

Update 2018-02-16 – 2: Updated Force Feedback > Shovas Custom FFB Files for EEC GT3 cars bringing it to a Candidate quality level.

Update 2018-02-16: Added Force Feedback > The GTR2 Force Feedback Engineer, inspired by the Project Cars 2 Race Engineer, which is an in-game question and answer car setup tweaking interface, to help narrow down how to tune force feedback in GTR2.

Update 2018-02-15: Added All Cars (Baseline) FFB settings under Force Feedback > Shovas Custom FFB Files for those people who just one one, simple FFB setup and don’t want to find the perfect one or who don’t want to change them in and out. Note, the All Cars (Baseline) FFB settings are simply the Certified HQ Cars FFB settings that I use as a baseline when starting to test any other car set. They just so happen to provide an acceptable FFB experience with most cars. I wouldn’t use it for everything but I can understand if some people prefer to just have one set of FFB settings.

Update 2018-02-11: Updated Force Feedback > Shovas Custom FFB Files for Original Cars bringing it to a Candidate quality level. Also added some methodology info for how I got about tuning FFB.

Update 2018-02-10: Updated Force Feedback > Shovas Custom FFB Files for Japan SGT300 Mod after some further work to get it to above average standard. Some of those Porsches feel really good, especially when you throw out the backend and feel it catch itself :)

Update 2018-02-10: Updated Force Feedback > Shovas Custom FFB Files for Super GT500 2005-2013 Mod and Japan SGT300 Mod after getting these to acceptable standards, although they still need work. Also added grades here to indicate how good the FFB for these cars feel. For example, HQ Cars have Grade A, or very good, FFB feel, EEC3 GT3 have Grade B, or acceptable/still needs work, FFB feel, and DTM Classics Mod has Grade C, or not really acceptable/needs work, FFB feel. I’ve added grades for each car set.

Update 2018-02-09: Noted my latest Field of View parameter, now 40.

Updated 2018-02-07: Updated Force Feedback > Shovas Custom FFB Files for Super GT500 2005-2013 Mod. I really enjoy seeing the FFB come into its own as you narrow in on the tuning. Feeling these cars come to life is an amazing experience. Sight and sound these cars are great and reviving the FFB brings the whole package together in a great experience.

Update 2018-02-30 – 2: Updated Mod Spotlight > EEC GT3 with some WIP thoughts. Added Getting Started > Community link and encourage taking advantage of the websites involved in the GTR2 community.

Update 2018-02-03: Added Force Feedback > Shovas Custom FFB Files including a table of FFB settings organized by Car Sets. Removed Force Feedback > My Personal Force Feedback Settings and Tweaking Notes as it was a little redundant after adding the Shovas Custom FFB Files section.

Update 2018-01-28: Added Mod Spotlight > Japan SGT300 Mod – Super GT GT300 Class Cars, Mod Spotlight > WSGT – World Super GT Mod (I’m impressed!).

Update 2018-01-27 -2: Added Troubleshooting > Crashes Loading Game, Mod Spotlight > Super GT500 2005-2013 Mod, Mod Spotlight > Subaru Impreza Mod, Mod Spotlight > FiaGT 2005 Mod, and minor edits to Mod Spotlight > DTM Classics Mod.

Update 2018-01-27: Added Peripherals > SimXperience AccuForce Direct Drive Wheel and TrackIR Head Tracking sections.

Update 2018-01-25: I’m a fan of Simracing Youtuber Jimmy Broadbent and he recently noticed my RaceDepartment post How much FFB can you feel in GTR2? 1/1000 of a percent (also a blog post of mine) and posted a video about his direct drive experience on GTR2 using the force feedback settings I recommended in that post: GTR 2 – How Does It Feel With A Direct Drive Wheel? Check it out, he seems to like it! I’m really happy to help some people get more enjoyment out of this oldie-but-goodie game.

Update 2018-01-25 – 2: Organized and cleaned up a lot of stuff in Getting Started, Mods and Force Feedback sections. There was a lot of clutter that I tried to weed out to make things more readable.

Update 2018-01-25 – 3: Posted my latest HQ Cars and Tracks “certified” UserData PLR and FFB tuning notes under Force Feedback > My Personal Force Feedback Tweaking Notes.

Update 2017-12-29: Added Known Issues > The Leader’s Advantage AI Bug.

Update 2017-12-08: CORRECTION: Time Acceleration is OKAY. Skipping qualifying sessions is a problem! Relevant notes about Time Acceleration updated.

Update 2017-12-03: Added Racing > How to Manage AI Difficulty in Championships. Added Known Issues > Time Acceleration Results in Unrealistically Fast AI Lap Times and Skipping Qualifying Results in Unrealistically Fast AI Lap Times.

Update 2017-12-02: Updated my latest personal UserData PLR file and my force feedback tuning notes under Force Feedback > My Personal Force Feedback Tweaking Notes. I’ve been experimenting going back to baseline ffb values and trying to reach a more iR/AMS/RF2 feel. I definitely prefer this in terms of drivability and reliability on the road.

Update 2017-11-10: Added Force Feedback > Guidelines for Tuning GTR2 Force Feedback. Updated Force Feedback > Rumble Strips Pushing/Pulling the Wrong Way to clarify wrong interpretation and now using default FFB parameter value.

Update 2017-11-09: Clarified Racing > Custom Daylight Acceleration works for regular race sessions but not 24 Hour races – they automatically time scale to race length setup when first starting the 24 Hour race.

Update 2017-11-08: Added Racing > Custom Daylight Acceleration. Added Resources > GTR Engineers Handbook and GTR2 Car-Owner’s Manual links. The GTR Engineers Handbook is particularly excellent for describe car setups better and more informatively than any in-game descriptions I’ve encountered before and the Q&A with real-life experts is also incredibly helpful.

Update 2017-10-31: Added Racing > How to Set AI Difficulty Level and Tips for Practicing and Qualifying for a Race sections. Also emphasized tip to avoid Time Acceleration as it causes a bug which results in overly quick AI lap times no matter what your AI difficulty level is set to.

Update 2017-10-29: Cleaned up and clarified Getting Started > Field of View. It’s now easy to understand and has an example. Fleshed out Force Feedback > My Personal Force Feedback Tweaking Notes with latest tuning adjustments.

Update 2017-10-12: Now using AI to AI Collision Rate=”40″ (max) as there’s no FPS loss for me so why not. Added Tips and Tricks > Avoid Time Acceleration to AVOID AI Bug Actually, skipping qualifying is the bug, Time Acceleration is fine.

Update 2017-09-22: Now using AI to AI Collision Rate=”32″ as I’m no longer experiencing FPS loss, maybe only stock tracks are affected and not HQ tracks. Try running HQ tracks if you have this problem. Added 5. Adding Friction and Damper under Force Feedback > My Personal Force Feedback Tweaking Notes. Added Force Feedback Settings under Getting Started > Modernizing as, while it may seem obvious, I wanted to highlight the need to do more than is available in-game to get closer to modern standards for FFB feeling. Added note about preferring HQ Cars and Tracks due to improved handling and grip adjustments in Getting Started > Modernizing > Mod: GTR2 HQ Mods Collection.

Update 2017-09-21: Added 4. Improving Corner Feeling under Force Feedback > My Personal Force Feedback Tweaking Notes.

Update 2017-09-17 – 2: HQ Cars & Tracks is working for me again after a fix. See comments under Modernizing > Mod: GTR2 HQ Mods Collection. Added Troubleshooting > Enable Tracing.

Update 2017-09-17: Added Troubleshooting section. Noted HQ Cars & Tracks was crashing for me. This works now, see comments under Modernizing > Mod: GTR2 HQ Mods Collection.

Update 2017-09-16: Added Tips & Tricks regarding turning up tire scrub and tire skid volumes and regarding refreshing old mod files if you’re experiencing instability.

Update 2017-09-15: Added Modernizing > 4GB Patch notes. Added GTR2 HQ CARS & TRACKS – 10th Anniversary and GTR2 HQ AI under Modernizing > Mod: GTR2 HQ Mods Collection. Added note that I’ve stopped using the Changing Weather Patch due to suspected instability.

Update 2017-09-14: Added Mod Spotlight > DTM Classics Mod with details for getting it running in 2017.

Update 2017-09-11: Detailed my FFB tuning in the section “My Personal Force Feedback Tweaking Notes”. Important! After a few rounds of FFB tuning I finally feel like I have a simple FFB setup that achieves car stability, quick response, and road feel. Added “GTR2 Crashes – It might Be Other Accelerated Graphics Apps” to the Tips and Tricks section.

Update 2017-09-08: Added “Disable Auto-pit and ai control” under the “Tips and Tricks” section. Noted tweaks in the “Make GTR2 Use More Cores For Better Performance” section under Performance. Added “My Personal Force Feedback Tweaking Notes” under the Force Feedback section.

Update 2017-09-06: Noted I’ve started over again from Julien Regnard’s FFB guide tuning FFB from baseline values instead of PLR defaults values under the “Helpful Guide for Advanced Force Feedback Tweaking” heading. Highly recommended. Don’t skip it like I did.

Update 2017-09-01 – 2: Added main section Performance and sub-section Make GTR2 Use More Cores For Better Performance to describe GTR2’s single-core use and how to get it to use more than a single core for better performance.

Update 2017-09-01: Added a Table of Contents for more convenient organization and to make it easier to find what you want.

Update 2017-08-30: Updated Force Feedback section to include more details on finding my optimal “FFB steer force average weight”, “FFB steer force exponent”, and “FFB rumble strip pull factor”. Also added “Force Feedback Tweaking Guide for Simbin Games by Julien Regnard” in Force Feedback section.

Update 2017-08-25: Added Changing Weather Patch mod under Modernizing section and added to Mod Spotlight. Updated my latest FFB settings in the Helpful Guide for Advanced Force Feedback Tweaking section.

Update 2017-08-20: Further FFB tweaking of “FFB steer force grip weight” which gives a feel of losing and gaining grip while cornering. Added Tips and Tricks section Use Auto-Clutch With Paddle Shifters. Added main section Mod Spotlight.

Update 2017-08-19 – 2: Added Getting Started sections: Mod: Track update for GTR2 Original Tracks, Mod: New GFX Mod, Field of View, Wheel Rotation and Wheel Lock, iRacing-like Brake Sensitivity for Potentiometer Pedals (eg. G27). Added Adding Game Cars, Tracks, Mods and More main section. Added Force Feedback main section with sub-section Helpful Guide for Advanced Force Feedback Tweaking.

Update 2017-08-19: Welcome to the initial posting of Secrets of GTR2! Check back from time to time as I add things and note the updates in this update box.

What is GTR2?

From the Wikipedia entry,

GTR 2 – FIA GT Racing Game is a sports car racing simulator developed by Blimey! Games and SimBin Studios (later Sector3 Studios) for the x86 PC and is a sequel to GTR. Since its release in September 2006, it has received widespread acclaim. The game simulates the 2003 and 2004 FIA GT Championship racing series.

And here’s the official game trailer,

SimXperience AccuForce Pro Steering System

Update 2018-09-28: Published a new post, Secrets of the SimXperience AccuForce Pro, in my Secrets series where I’ll be recording the less obvious/less intuitive discoveries and tips and tricks with the AccuForce and SimCommander. I’ll be putting AccuForce Game-specific content over there from now on.

Update 2018-02-24 – 2: Added Tips and Tricks > AccuForce causing spurious inputs / Inability to assign controls in-game due to spurious inputs section detailing a fix if your AccuForce is causing spurious inputs.

Update 2018-02-24: Organized with a Table of Contents.

Update 2016-11-15: My latest R3E settings, including the November 2016 update, are over at my RaceRoom Racing Experience Force Feedback Settings post.

Update 2016-06-10: Updated Assetto Corsa FFB settings a little.

Update 2016-03-31: After the R3E update, I was getting a constant vibration in the wheel that tracked the cars speed (not engine rpm). People said to zero Slip Effect in-game but that wasn’t working for me. I eventually created a brand new R3E controller profile in-game and then compared to my previous profile. I noticed some differences like “FFB steer vibe freq mult=0” (and related values). Once I synchronized those I changed Slip Effect to zero in-game and that solved it.

Update 2016-03-08: Clarified certain language after time and reflection per the Closing Thoughts section. Filled in some sections that were still left undone.

Update 2016-02-19: Updated R3E section to sync with update notes. Added Assetto Corsa and rFactor place-holder sections for now. I plan to add more as I setup those games to work nicely with the AccuForce.

Update 2016-01-12: Added Suggestions for Improvements section.

Update 2016-01-01 – 3: Continuing my RaceRoom Racing Experimence experimentation (see updates below) I have been trying different cars with the settings I came up with earlier. I’ve run the Cadillac CTS V.R, BMW M4 DTM 2014, and the Aquila CR1, all at Brands Hatch Indy. They all felt really great except the Aquila which had very heavy steering (I’m not sure if S3 has updated the car in a long time) and its shift effect is ridiculous, I’ll have to turn that down even though it’ll also effect the other cars. I’ll be trying more cars and more tracks as my next step… Tested the McLaren MP4-12C, Ford Mustang GT3, Audi V8 DTM 1992, and 134 Judd V8. They all feel way better than my previous settings. The only quibble I have is cars with heavy steering could feel better. Remember some cars do not have updated physics/ffb (like the BMW E30 Gr. A I just tried) and they feel particularly “numb” or “dull”.

Update 2016-01-01 – 2: Following on my RaceRoom Racing Experience experimentation earlier today (see first 2016-01-01 update below), I then started experimenting with Wheel Modes and Dynamic Force Boost (expand Sim Commander Effects > Game Force Feedback to see the checkbox). I felt like I had more grip or could better tell how much grip I had under the Responsive (Peaks Allowed) mode as opposed to Default Wheel Mode I was using. This wheel mode allowed in some more what I call “boat sway” in the steering (ex. high speed straight wheel oscillates back and forth on its own) but it’s not so bad. I then enabled Dynamic Force Boost and the feeling of grip improved a little more. As a bonus, force feedback effects come in clearer due to the added force strength added by the wheel mode and force boost. I then had to experiment again with SC Dampening and Friction and I ended up on 1.57% for both. By the way, I have so far kept both Dampening and Friction to the same value as it feels correct in the steering and also seems to make sense in that they are sort of opposites and complement each other in a way. Dampening feels like added “weight” during force feedback effects, such as when the wheel swings back the opposite way when the backend goes out and you need to push through the effect to correct the steering, whereas friction adds weight when there are no force feedback effects. It’s still not perfect, I need to test with other settings like SC Inertia, as I said, and also try other cars (so far testing on BMW M3 GT2 at Brands Hatch Indy). Here are my latest Sim Commander and in-game settings for R3E:

r3e-sc-settings-20160101br3e-settings-20160101br3e-settings-2-20160101b

Update 2016-01-01: In RaceRoom Racing Experience, I experimented with moving Smoothing, Spring, Damper, and Friction to Sim Commander settings, so these are disabled (0%) in-game. I figure all the AccuForce does is FFB so it might be better or at least more efficient than the in-game settings. It also consolidates as much as possible to the wheel to avoid duplicating settings. I noticed both SC and R3E had smoothing applied so I first disabled it in-game, which felt better, and then disabled it in SC, which felt even better: I realized I was now feeling effects quicker than I was before. It seems Smoothing was delaying effects or making it feel delayed. I then did the usual binary search on SC Smoothing and Dampening and landed on 8.24% for each. It doesn’t feel perfect but it’s the best I could do in the binary search so far. I might have to experiment with some other SC setting like Inertia. Oh, before I started I did Reset to Defaults on the wheel, ensured Wheel Mode was Default (because High/Responsive modes have had too much oscillation in R3E), disabled Engine RPM (also SC), and then started experimenting in-game. Here’s my latest Sim Commander and in-game settings for R3E:

Update 2015-12-24: Added a Closing Thoughts section which wraps up my thoughts and feelings after having driven with the AccuForce now for more than 6 months. What do I really think of the AccuForce? Would I buy it again? Read on to find out… Oh, and here’s an article over at MockRacer.com about the Leo Bodnar SimSteering2 wheel where he compares it the AccuForce he tried earlier in the year. The direct drive wheel market keeps getting more and more interesting.

Update 2015-11-26: I picked up Stock Car Extreme on the Steam Fall Sale ongoing right now. Not a bad pikcup for CAD $20. Sim Commander supports it right out of the box with pretty good settings. I made a new SC profile from scratch and reset it to defaults. When you launch SCE for the first time remember to set Windowed mode or you won’t see Sim Commander’s overlay in the game. In game, you’ll need to setup your controls as per usual for any sim. It doesn’t feel like SCE knows about the AccuForce so I had to set the Wheel Range (in the Controls screen just after you launch a track but before you get on) to 900. It still feels off, you might need to set the Wheel Lock in the Garage screens to 30 to get a 15:1 steering ratio (ie. something like GT-style steering ratio). Let me know if there are any more settings we AF owners should be setting for a more solid ride. Enjoy.

Update 2015-09-25 – 6: My latest Sim Commander settings for R3E:

sc-r3e-2sc-r3e

And for R3E in-game:

RRRE 2015-09-25 23-49-00-52RRRE 2015-09-25 22-57-04-73RRRE 2015-09-25 22-57-08-21

Update 2015-09-25 – 6: A note on dialing in range settings. I’ve mentioned it before but I think I’ll mention it again. When I come up with settings within a range (ex. Smoothing 5% where the range is 0% to 100%) I do a binary search by hand. Put simply, a binary search is starting at one extreme, adding or subtracting half the range, and then adding or subtracting half again, based on preference, and repeating this process until you find an optimal value. For example, with Damping I went from 0% to 100% to try the extremes, then 50% because it was too high, then 25%, then 12%, then 6%, all based on preference. So, put in the setting, run a lap and, if it feels too much lower the value or if it doesn’t feel enough raise the value.

Update 2015-09-25 – 5: I’ve been playing around with Smoothing (5%), Damper (6%) and Friction (6%). Smoothing was at 25% before and it was taking a little bit of definition out of the ffb so I put in just 5%. Damper was at 0% before and it tends to simply dampen all forces (sort of make them slower) and I found more dampening helped me catch sliding backends. Friction was at 0% before and it applies a resistance to the strength you put into turning the wheel. I found in slides or losing grip that something felt off, it was too easy to swing the wheel back and that caused me to misjudge how I correct a slide. Turning up friction to 6% (after trying a binary search) helped me just a little better about how to correct my steering in those scenarios.

Update 2015-09-25 – 4: Even though R3E doesn’t officially support the wheel yet I find I’m finally getting to like the AccuForce FFB results after a lot tweaking (see the updates below from the last few days). The only thing really bugging me right now is the boat-like swaying motion on straights (“floaty” steering feel near center) and also the awkward steering feel when your backend flies out and you need to counter-steer. Something’s still not right there. But, hey, things are feeling pretty enjoyable.

Update 2015-09-25 – 3: I experimented in R3E with Steering Rack FFB. I was used to 0% (ie. all forces from tires as opposed to steering rack) so I flipped it 100% (ie. all forces from steering rack as opposed to tires) and I noticed a more “gradual” or “analog” rise and fall as I mounted and dismounted kerbs. I quite like the extra information so I’ve currently settled on Steering Rack 50% (ie. half of all forces from tires and half of all forces from steering rack).

Update 2015-09-25: Tweaked R3E Steering Force Intensity and Understeer as I put in more seat time and learn what I like.

Update 2015-09-17: Added force feedback settings for RaceRoom Racing Experience. Basically I reset the Sim Commander Profile and then set Steering Force Intensity 70% 50% and Understeer 25% 20%. That’s all I’ve done so far.

Update 2015-09-15: Having problems with Sim Commander crashing after launching games or the in-game overlay not showing in some games like RaceRoom Racing Experience? Power cycle your AccuForce and it should come back. I knew this trick since I ran into a bug when I first got the wheel where the computer wouldn’t even boot with the AccuForce on. Since then I must have gotten into the habit of turning the AccuForce on shortly after booting and that was causing problems. If I only power on the AccuForce after logging in then RaceRoom appears to work flawlessly and I don’t need to power cycle.

Update 2015-07-30: Check this very helpful and informative post on tuning the Accuforce Pro: AccuForce Settings For Dummies.

Update 2015-06-03: Added RaceRoom Racing Experience after 2015-06-02 Update section.

Update 2015-06-01: Added Auto-Tuning with Sim Commander Software section. Recommended read for AccuForce owners: AccuForce Tuning Feedback Test. This is a thread Berney of SimXperience created after the Sim Racing Garage head-to-head video, mentioned below, attempting to provide collect some user experiences and determine what kind of changes could be made to the wheel to improve feel for sim racers (who may have different force feedback tastes than real-life race drivers).

Update 2015-06-01: Barry, from Sim Racing Garage, has release a head-to-head comparison of the Accuforce Pro, Bodnar, and OSW wheels. It has highlighted some nagging concerns I’ve had ever since I’ve been playing with the wheel. Before we go any further, don’t think for a moment I’m saying the Accuforce is not a good wheel. It’s a professional, supported, warrantied, complete package, direct-drive, very strong wheel, with good force feedback and excellent tuning options. It’s a great wheel and at a competitive price. What I will say though is that the forces are not coming through as much as I’d like. For example, one reviewer in the video mentioned how it was difficult to tell the different between a slide through grass and the moment it hit the pavement during the slide. The AF wasn’t communicating that well. Other examples include strong cornering forces washing out road feel, or banking or kerb forces not feeling as defined as the other wheels. On the SimXperience forums, Berney (of SimX), has said he’ll be thinking about pushing out wheel updates to work on the comments the reviewers had in the videos. I look forward to trying those updates.

SimXperience AccuForce Pro Steering System

accuforce2I’ve recently received my SimXperience AccuForce Pro and have been enjoying it for the past week. I’ve only owned one other force feedback wheel, a Logitech G27, and this is, of course, leaps and bounds beyond a G27. There is ample power and tuning options to provide the flexibility sim racers really want to ensure the best and most realistic experience while driving.

I’ll be posting my initial thoughts, my driving and tuning experiences, and providing tips and tricks for various facets of the wheel, it’s tuning software, and for the various sim titles I play.

I’ll be writing this post in parts and updating new sections as I have time and learn new things about the wheel!

Enjoy!
