This game has been reported to be incredibly buggy, particularly towards the ending.
My advice would be to shut down all background applications, i.e. your internet browser, your downloads, music player etc etc. It'll free up some RAM on your computer and the game can then use it to run a bit more smoothly.
Wouldn't getting more RAM help as well?
It freezes for almost everyone.
This game is very buggy, so it's not your specifications, it's the game itself. If you're experiencing problems during gameplay, just lower the video settings a little bit and you should be okay.
yah it stuckes for me 2 damn i were just goiing to finish a great race and it freezed :cry:
