me too
I tried to fing out a regularity - no chance...
I think the cause of the trouble is to find in USB polling:
For a part of a second the wheel is away an then its
suddenly back again. The LWFF GP interprets this as a hard
input (hard right/hard left steering) of the user an let it
feel you. The twitch is happening too w/o FF enabled !!!
Perhaps it is possible to solve the problem using an PCI USB
card instead onboard USB, who knows !?!?
If I find out more, i will tell you...
