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 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 2019-12-28 (3): Added some XD tweaks to move the Tire Temps (Motec) box to avoid covering flag indicators by default.

Update 2019-12-28 (2): Updated NVIDIA Inspector Settings to my latest.

Update 2019-12-28: Check out the Sounds of GTR2 Mod for a complete revamp of the audio of all original content cars. I really like these sounds. Where the originals sound very synthetic, these have a rougher, more raw feeling to them, which I prefer and to me sound more realistic.

Older updates are archived at the bottom under the Updates section.

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,

iRacing Force Feedback Settings

Update 2017-01-02: I’m now updating FFB information over on my Secrets of iRacing post.

Update 2015-02-26: I’ve been changing up my FFB settings in iRacing lately after realizing that linear ffb resulted in such low force strengths (to avoid clipping) that I wasn’t really feeling the road anymore. The ffb changes were just too subtle. So, because I have a low-end wheel, a G27, I’m now using non-linear ffb and doing the usual binary-search to find the optimal force strength to avoid clipping. I’m doing this only because of my relatively low-end, entry-level G27. I expect the recommended usage for higher strength wheels (T500s/T300s, Fanatec ClubSports, Accuforce Pro, etc.) should still use linear ffb.

Update 2015-02-26 – 2: For the record, a binary search is one where you take your current value, determine whether it’s too little or too much, and then double it (when too little) or halve it (when too much), and repeat that process at each new level to dial in on your optimal value. For example, for iRacing force strengths I might start out at 32, decide that’s too much and go to 16 (half of 32), decide that’s too little and go to 24 (16 + 8 which is half of 16), decide that’s too much and go to 20 (24 – 4 which is half of 8), decide that’s too little and go to 22 (20 + 2 which is half of 4), decide that’s too little and go to 23 (22 + 1 which is half of 2), decide that’s too much and go to 22.5 (22 – 0.5 which is half of 1). This is a real example I just did in iRacing a few minutes ago on the Mazda MX-5.

Update 2015-02-26 – 3: Nvidia users should check out these threads: iRacing graphic optimizations for NVIDIA users, Guide: nVidia iRacing Antialiasing (AA) Settings, NVIDIA SLI Compatibility results. The second guide about AA gives some good settings for Nvidia Inspector (I use in-game 4x AA with Nvidia Inspector AA – Mode “Enhance” and AA – Setting “8xS [Combined: 1×2 SS + 4 MS]”. Read the thread for what they mean). The third thread is about SLI and getting rid of microstuttering (I use Nvidia Inspector “SLI Compatibility Bits” = “0x00402015” per the thread). It’s not perfect but it’s better than in-game AA and should give higher performance.

iRacing Force Feedback Settings

I’m a big fan of iRacing sim racing and I frequent their forums quite a bit. I’ve seen a number of posts, over time, on the iRacing forums about people asking for the right force feedback settings for their wheels. As it turns out, this info in its complete form is harder to come by then you might think so I’ve decided to post everything I know and have implemented for my Logitech G27 for force feedback in iRacing…
