Hi, When you go into the tuning menu (on the car section), to view an alternate skin, etc. It varies from car to car, but I can select a car, and my entire screen goes gray w/red lines. Can't CTRL+ALT+DEL out, nor window changes. It locks up my PC. If it helps, I have selected "garage" instead of "spinner". With F2, it takes less than 5 seconds to lock up, Skippys, and 1960s series take around 3 minutes, and Clios are stable. Just from observations. I know rf2 dislikes AMD vid cards. My PC specs: AMD Phenom II 955BE (stock clock) Sapphire Radeon 7850 OC 16GB RAM Win7 64bit If you need more research, just ask, I'll be glad to help.
This is probably an issue on your end. If you didn't already perform a clean install of rF2 latest build 134. Update graphics drivers - you can try latest or some older ones. You can also try to updating your other drivers (specially motherboard).
