Does it have the same FPS Issues as the Steam Version? When i bought the Game on Steam, i got like 10 FPS, which made the Game unplayable... thanks to the Steam refund, i got my money back. So before buying it, can anyone confirm that it runs flawless on Win7 64bit?

I haven't noticed any. I'm on Win7 BTW.

Ran fine for me on Windows 7 (with an AMD card) as well. But some people had and have serious issues with it:
