I have very little problems and it runs great. I have a GTX970 and AMD 8 core CPU. I run it in 3340 X 1080 Windowed, stretched over three portrait landscape portrait monitors, with TrackIR working. I can race 55 AI in Weather and day night, no problem. Just did a 6 lap race last night on Nords combined. So I'd guess you have a individual computer problem. Oh, I don't do multiplayer.
