I got this info from a post by Scott Drake at a F1 racing website. To do this, you need to locate the plr file for your player and change one setting. Here are the steps: Find your rFactor install folder. In my case, it's c:\Program Files\rFactor Click into the UserData folder You will see a folder for each user profile you have created in rFactor. In my case, I have Scott, AI Player, test 1, test 2, etc. I open the Scott folder There will be a file name <profile name>.plr. In my cass, Scott.plr Right-click the file and choose open with > Notepad Press keys <ctrl>+f and type or paste Cockpit Vibration Mult1 You'll like land on the line Cockpit Vibration Mult1="1.00000". Change this value to 0.50000, as well as the value for Cockpit Vibration Mult2 to 0.50000. Save the file and restart rFactor. See if that makes it better. If not, set the value lower all the way down to 0. I prefer to leave some head shake as I feel it adds to the immersion. Hope it's ok to post this. I know it helps me reduce headache also.
