Hi,
I had a jittering issue with the FFB on my wheel (a G27), which is related to feedback strength.
It happens when no "centering force" is applied on the wheel: in straight lines, when being still on the starting grid, or when lowering the car in the pits (when the car hits the ground).
My wheel oscillates around the center a lot, so much that I have difficulty keeping a straight line with one hand: the shocks are powerful.
At 60% FFB strength, it doesn't happen much: when the car doesn't move the jitter stops by itself, flat out in a straight line I can handle the wheel with one hand.
At 90% strength or more, it's quite problematic: when the crew lowers the car the wheel oscillate more and more wildly, same on the starting grid, and I really have to get a good grip at high speed to avoid crashing.
And obviously, the wheel gets really hot since the motor is always pushing. ( after a full race the casing of the wheel is almost too hot to touch)
It's particularly sensible in Interlagos, which is a bumpy track. I don't recall having that behavior before ( i mean several years ago). Is there a tweak / setting I could modify to reduce of amount of shocks i'm getting ? ( and only these, other FFB effects are ok)
