DiRT Rally 2.0 game update 1.4.1 is available today, primarily focused on force feedback for steering wheels.
The team has changed the way the ‘Suspension’ setting works, as the slider has been set at a default level of 100 for all devices. Of course, this can be changed to suit your preferences.
If you prefer the way the game felt previously, go to the Input section of the Options and Extras menu, select your device and adjust the ‘Suspension’ slider in the Vibration & Feedback tab back to 0.
The Principal Game Designer and Senior Programmer have put together an Input Device Guide, which you can read here.
