That's because my card is oldish, and 12.4 is stable. Unlike more recent drivers. It was how I got something -- Civ5? Skyrim? FNV? -- to work properly. Forget which game I was having issue with.

In the options screen, try to switch of the gel ui.

This was 13.9, which was what ATI recommended for my card. It had no effect on anything that I could see. Or to put it another way, I still can't see squat on the main screen. Also, I enabled crossfire.

Disable crossfire

Hey guys, we have tracked this one down, and are working on getting it fixed ASAP. It has to do with compute shader support, so if you can update your drivers, as been pointed out, it can fix it. 

That said we are working on a fix for DX10 cars that do not support Compute shaders.  

Thanks mormegeil!
