Yes, and I also had an issue where the PC2 Controller save-file became corrupted and negatively influenced the FFB behavior. One of the several indicators of said corruption is that various cars require bigger changes being made to the Tone setting in order to achieve balanced and consistent FFB. Some other indicators are lack of under-steer feeling, poorly timed response to wheel-input, and general inconsistency in FFB among various cars that lead to broader changes to FFB-settings and / or searching for the right combination of settings / preset.
Initially, when I switched between DD-systems (AF to OSW), I found it necessary to reduce the FX to or near zero. The very next time I played PC2, I found that the FFB settings have to be altered significantly but, I still could not achieve the same results I had enjoyed initially.
It was suggested that the solution was to delete the “defaultcontrollersettings” save-file in: Documents > Project Cars 2 > savegame > #folder > project cars 2 > profiles.
This will require assigning and calibrating all controllers but, the results were immediate and very apparent. I suspect this issue is not so widely known because it’s not as apparent when using consumer wheels as it is with the OSW but, I do see quite a few complaints by PC2-players having similar issues with FFB.
