XFX Nvidia 250 GTS 1GB. Gameplay runs great on ultra settings, cinematics fail terribly. Screen goes black, then comes back, game minimizes comes back etc. Makes viewing cinematics extremely frustrating and just about impossible. Prob would fully crash if I was running XP. Running W7 Pro x64. This 250 GTS is a warranty replacement card for an 8800GT which failed about 6 months ago. I am sure it is the card because I replaced with nvidia 8400 (so ugly) and cinematics (although awful looking) ran without an issue. I have reseated the card, redownloaded drivers, ran sc2 repair tool and even just reformatted.
