My AccuForce feels smooth in the forces I'm feeling throughout lap 1 including low and high speeds but by the end of lap 1 I'm always encountering this 'nervous shake' that ramps up with speed. I experience good FFB in iRacing, AMS, and others, so it's something with up with this combo in particular. It almost makes me think it's a tire warmup thing. I make sure not to get on the grass or hit anything (I have damage disabled anyway) but it still happens. Any ideas? Is there some force that comes in as the tire warms up or something else about the car 'comes in'?
