Welcome to Secrets of rFactor 2 where I will be recording my experience, tips, tricks, resources and other helpful information as I get into rFactor 2.

Secrets is a series of blog posts I started with Secrets of iRacing and which has grown to include Secrets of GTR2, 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 2018-07-26: Tip: For in-cockpit FOV adjustments try the Multiview Adjustment tool by pressing CTRL-= while in-car in the pits. Thanks to this post on for highlighting it.

Update 2017-10-12: Initial publication.

What is rFactor 2?

From the Wikipedia article,

rFactor 2 is a computer racing simulator developed by the American independent software firm Image Space Incorporated, released for Windows in 2013. Like its predecessor, rFactor, it is designed to be modified and is used by professional racing teams for driver training and race car development. Much of its source code is derived from rFactor Pro which is also used by professional racers and most of the Formula One teams and NASCAR manufacturers.

And here’s a visual taste of the game,

Getting Started

In Secrets of X, I try to focus on the non-obvious or unintuitive so I won’t be covering basics like getting the game, installing it, tweaking graphics or force feedback. You’re probably beyond that yourself so I’ll focus on the hidden and obscure things.

For reference, my system specifications at time of writing: Intel Core i7 2600K @ 4.8 GHz / DeepCool GAMMAX 400 CPU Cooler / ASUS P8Z68-V / 16GB MEM / 240GB SSD / Gigabyte G1 Gaming NVIDIA GTX 980 Ti 6GB / 3x Benq GL2760H NVIDIA Surround / SimXperience AccuForce Pro / Logitech G27 Pedals and Shifter / 3x GTEYE Pedal Springs / Obutto R3volution / Logitech Z906 5.1 Surround Sound / Windows 7 64bit Home

Inverted Force Feedback

If your force feedback feels wrong, like it’s on the ‘tip of a knife’ or like you’re balancing on a barrel, it’s probably expected inverted force feedback from the game. I’m not sure why this isn’t exposed in the UI but here’s how to fix it:

  1. Find and edit your UserData\Controller\*.JSON controller file
    1. Eg. Mine is located here but yours will be different: G:\SteamLibrary\steamapps\common\rFactor 2\UserData\Controller\AF.JSON
  2. Find the “Steering effects strength” parameter and set it to the opposite of what it was. In other words, if it was 10000 then set it -10000, or vice versa as needed.

SimXperience AccuForce owners will need this!

Field of View

rFactor2 has a great built-in FOV tool. Simply press CTRL-= while in your car and you’ll get a visual tool to help. Thanks to this post on for highlighting it.

Old info about setting FOV manually:

rFactor 2 uses Vertical FOV so check out this Google Docs spreadsheet for common monitor size/view distance fov mappings. If that link dies at some point, see this thread which describes how to calculate the value (it’s where I found that doc in the first place).

Use’s rFactor 2 FOV calculator for easy and exact calculations. Also supports Assetto Corsa, rFactor 1, Game Stock Car, Automobilista, Project Cars, RaceRoom Racing Experience, and older SimBin titles like Race07 and GTR Evo.

Tips & Tricks

Low quality textures

Keep texture detail settings as high as possible even if you’re lowering other graphics options to achieve higher frame rates. Textures tend not to be too heavy so you can keep good textures while lowering other graphics options to maintain higher frame rates.
