What are your specs Solidus?
Just realised the recomended GPU is a GTX660 which is pretty high, I have the EVGA GTX680 Superclocked version but I'm thinking of getting the Gigabyte GTX980 G1.
I have a GTX 780, 8 GB of RAM, Windows 7 SP1, so the game should run without any problems. It's certainly not unplayable by any means, but the stuttering does get a bit annoying after a while.
