I'm running a GTX 295 with the latest nVidia drivers. When I utilize SLI, my game gets stuck at the loading screen, though the loading finishes and the music is running in the background, I can't see the town. When I alt-tab out and tab back in, I see the graphics but with major artifacts flooding the screen.

When I run the game in single-GPU mode, the game loads just fine.

I've tried windowed mode, full screen, various refresh rates, vsync, to no avail. Any ideas to get SLI working?
