Same here with a 5870. every time I finish the mission, I get a freeze at the loading screen. Releasing an unfinished game for $60 bones is bad mojo, mofo. Bethesda placing the entirety of the blame on drivers is even worse.
man i just got the textures to run all nice too, nothing wrong with the game besides the crash and a couple of flickering enemies.
