My Formula Rim always vibrates when DD1 is powered on. I've tried my Formula Black and my Clubsport Porsche rim have no vibration issues. My drivers are up to date, as far as I know. Has anyone else had this problem?
Could be your driver/firmware. I had the same problem with vibration through the wheel when on v347 so I have gone back to v346 and it's working great now. I don't use the beta drivers at this point as I have had problems and needed to return my first DD1 for replacement. There's no evidence to suggest bugs can't destroy or create bugs with either your wheelbase, wheels or even your PC. Anything with unstable software can create havoc.
