I've never experienced these vibration motors simulating shocks and bumps on PC. Are you certain of this or could it be a placebo effect? Someone else say something, I'm confused
F1 on ps3 is the only game where I thought the sho gave me more rumble strip feedback, but it didnt get weaker when I turned it off, so I'm thinking placebo, as it only vibrates when I press the accelerator.
This is normal! The XB 360 supports vibration, the PS3 not. Make a new profile for your PS3 and set sho in the wheel to 0. Alternatively you can activate ABS.
