Please, help me. I've followed the guide and everything worked perfectly, my g27 became a totally different wheel with very good ffb. But, after that assetto corsa gave me a "version mismatch" error and sort of a reset, my "ff_postprocess" file in Documents/AssettoCorsa/cfg continues to reset every time I start the game. I modify the file as written in the guide, I save, and it remain that way any time until I start the game. After I have started it, it changes back to standard and in fact the ffb is really bad. Can you help me sorting this out? I'm going crazy. "ff_process" in Drive/SteamLibrary/Common/AssettoCorsa/cfg is setted proparly and doesn't change, but it looks like this is ignored while the one in Documents is resetted continusly and used.
If the notch goes away with default settings you have too much force around the center. For me the notch also comes back when you remove the "tremor" as you call it. The wheel motors lose the "constant little energy" and you feel that hole then.
I'd suggest you put the tremor back in and just reduce the overall force feedback until the tremor and the notch fade away. That's what I always do with Numpad +/- for each car. + until the deadzone vanishes or - until the notch fades away :)
