This is driving me nuts, and I've spent the past week trying to figure out what's going on. Using my Fanatec Porsche Turbo S wheel in rFactor, no matter which mod I use - Enduracers, ILMS, etc. - and which FFB I use - RealFeel, rFactor default, the new 'FeelsReal' - and which FFB settings I use - Low, Medium, High, Full - and no matter how many FFB parameters in Controller.ini I drop to zero - steering shake, braking shake, etc. - I can never, ever get rid of an extremely annoying shaking of the wheel that begins from the second I enter the garage. It occurs mostly around the center position. It's a strange "spiking" behavior that throws the wheel left or right very quickly, making it difficult to accurately control the car. I don't see this kind of behavior in any other racing sim/game ... and it seems to happen in every single car I drive in rFactor. Has anybody else experienced this? What about those with other kinds of wheels? Do you get a never-ending and random "spiking" of jolts about the center position? Is there any way to get rid of it?
