The Game looks Amazing no doubt but the controls are terrible. I have played with every possible setting to get my mouse to move smoothly but it just doesn't want to. Sensitivity high, Sensitivity Low, In Game and Out of game. It just doesn't work. I never had any problems with this in the first Crysis. I want my money back.
Oh.my.god. Every time I see some complaint I get :I want my money back. Get Wasdie's Advanced Options tool and Try disabling mouse acceleration. Then see what happens.
