Because you're constantly spreading misinformation based on feelings and hunches and not on facts.wolf you always lurking, waiting for me to make one comment about something not feeling right. you dont know how i feel, and how do you know they are not testing something.
If AMS2 feels completely different to you from day to day when there haven't been any updates for at least a month, then the problem is that your installation/PC are somehow volatile. Shut down background programs and use VSync/frame limiting (-fpscap xx on launch commands) to have a constant frame rate, and recalibrate your pedal ranges at the beginning of every session to avoid calibration-related issues.
To answer your other question: Turn your wheel all the way to one side, then turn it the other way until it is the number reads 900 degrees (if that's what your wheel is set to in its calibration).
