Hi,
I have the same exact problem with the game,
i dont think SP1 will solve anything, because my game is umm downloaded and doesnt run on cds,
the problem is with the video card, i have the same and exact video card. i still havent figured out what the problem is, i had the same problem with COD ( Call of duty ) same and exact problem, ive read that i have to turn off fast write in my ATI options, and it worked, but still NFS doesnt!!! lol so i dont know what to do, i have a real copy of XP ill try downloading SP1 though i doubt this is gonna work, but if it does, ill get back to u guys
