Now first and foremost I believe after playing a few hours, about 2-4hours. My memory becomes completely expended while playing on low settings. So long story short is that I had to restart one time because I noticed it a little. Second time had my computer restart on its own right after hitting return to garage after crashing. I believe this is mainly a ram problem on my end. So expect some problems if you are on the low end I guess is what I'm saying.
All in all I think the game runs pretty well so far. Maybe some kind of warning though like I've seen on World of Tanks once that I encountered.
EDIT/UPDATE!: Problem seems to be fixed now. Yes I'm still using windows xp and think it was something to do with the game! My video card was not heating for sure! It was game-side in my opinion. After the lates patch my computer now doesn't restart! The problem usually occurred when hitting garage after playing a game after I've played 5-12 or more games. I do play the game on lowest settings possible and know my computer's processor is quite old as well and think it was still more of a 32bit system/ram issue with the game since I have'nt had it happen since the latest patch.
