    I do recall Ian Bell talking about changing the Controller input Filtering at one point, mainly to help oval racers, I wonder if the thustmaster was negatively effected by this change? Isn't it more precise then the Logitech?
    There are code differences between wheels for sure, but not in the physics code as there is nothing in the physics code related to the wheel that is used in the first place. Any perceived car behavior differences between wheels can only be induced through the interaction of FFB with the player.

    And controller filtering is not applied to wheels, only to controllers.

    With the right to say what you think comes the obligation to think about what you say.

    I think the differences between wheels is about design philosophy, specifications, materials, manufacturing tolerances and quality control of the wheels themselves, a software developer would frankly, be going out of business very soon if they where fronting development costs coding for every wheel and wheel variant in the marketplace.. It makes no economic sense...

    Well, FFB needs to be optimized for each (major) wheel on the market for sure. But coding a physics model dependency on the wheel type does not make sense and indeed isn't there in pC2.

    Hi Sankyo, was it that the FFB was 'optimised' or was it tested and then the default settings for a wheel based on the results of the testing within the defined parameters set for feedback... If that makes sense? Just wondering...

    I don't know what goes on behind the exposed FFB parameters depending on what wheel is used, there could be different low-level settings to bring out the best FFB on each wheel, or just different defaults per wheel.
    Personally I think it's the latter, but not sure.
