Yeah, there's a problem with MSAA, but it's certainly not the end of the world. With all the other settings cranked up I don't even have any VRAM (or performance) to spare on MSAA, so I leave it off anyway and just use FXAA. All in all I'm happy with how good it looks and how well it performs on my 7950 (most of the settings turned up, staying at 40+ FPS)
