I've been using an 8800 GT (169.21) in my Core2 system for a couple of months. The one annoying thing I've noticed is CPU usage. With v-sync enabled and running full screen, it's consuming 100% of one core. So far as I can tell, the DirectX Present() call is busy-waiting for the next v-sync. It doesn't do this when running in a window, or with v-sync turned off. Considering the project I'm working on normally consumes 3% to 5% of the CPU power at 75FPS, this is not something I want to see.
Anyone else heard of this problem? I've been casually googling around for it since I noticed this, but have not yet found anyone mention this side effect.
The only game-related problems I've seen so far is with Arx. After swapping the old 7900GS for the 8800GT, Arx renders the screen strangely with lots of flickering. It really looks like the game is displaying whatever is in the frame buffer while the frame is still being rendered -- wall geometry mostly doesn't flicker, but detail meshes flicker constantly.
