No problems at all with the demos and now that I have the full game, I can'e even play it.

The game freezes and causes my pc to BSOD. Man what a pain. I hope there is a patch soon.

Looks like there have been several reported problems with the A64 and the 6800GT cards. Too bad I did not see that before. I guess it would not have mattered since the demos ran fine.

Dunno.
