Hi guys. Up to now I´ve never had problems with rFactor 2. But yesterday it got me: I was driving the Aston Martin in Silverstone, when suddenly strange green, purple and yellow artifacts appeared on the screen. Then rf2 freezed and changed to the dekstop view. You could hear rF2 running in the background. I deleted cbash and shader folder and gave it a another try. The track loaded 100% and the "standings screen" showed up....with that strange artifacts. rF2 crashed to desktop and stopped workind. My screen went black for about 2 second, a message popped up on the bottom left of my screen. "Nvidia kernel driver has stopped working. Driver get restored" ( Sorry, English isn´t my native language) The screen went black again, and so on. I did a safe reboot and installed a older driver a had on the hard drive. (new installation) I restarted my computer normally and the screen went black again. Then I manually deinstalled this driver and after that a installed the latest nvidia driver for my gtx 680. The problem was gone. I did some GPU tests, bc I thought my card is going to die, Temperatures are about 61°C, so no thermal problem I guess. I started rF2 again (Silverstone, Aston Martin) and after loading the track, I saw the cockpit of the car is white, as some guys mentioned in other threads before. About a second after that, rF2 crashed again. Nothing has changed since the last time I enjoyed rF2. Just some updates for the challenger pack. Did you have any clue, why this is happening? As soon as I am @home I will try if resubscribing can solve the problem. But I didn´t have any error message during the challenger pack installation. Cheers guys!
