Crysis 2 is easier to run than the original, especially if you don't turn on DirectX 11 mode. Your card will definitely handle the game well at such a low resolution. The 570 is meant more for higher resolutions like 1080p. At your resolution, I see no reason why your GTX 570 wouldn't be able to max out the game, with or without DirectX11 features.
Okay, just for clarification, I can run this at a consistent 30fps with DX11? Or will it be jittery? I want 30fps minimum
Just really making sure, guys.
