I've noticed some strange FFB on the S/F straight as if the grid spots have bumps, also an odd one through Woodcote that was never there before (GP & International layouts)
Noticed the same issue when driving over the garage spots at Indy. The faster you drive the less apparent it gets, but when you go slow it is as if you are driving over some briks.
Same here but less noticeable with the Nissan GT500 car. AI cars seems to hit these bumps much worse than players. I don't remember which cars but some have actually flipped on these bumps at Silverstone straights.
I've not noticed any AI suffering the same issue, I was thinking that maybe what with starting SteamVR first to make FFB work that perhaps there's a glitch with it.
I've got spinned by that bump a few times, I checked in the replay and noticed that there's some painting over there that is well above the road surface. It seems that the grid spot paintings cause all these bumps on the straights...
