I got the metro 2033 demo. I am wondering if i enable MSAA 4x and disable Tessllation and DOF and play on very high settings on 1920*1200 or use AAA and enable DOF and Tessellation in order to improve the performance in Very high? Because i tested it. if i enable 4x MSAA and disable DOF or DOF and Tesslation, the gameplay is very fluid. so which one of those is noticeable if i disable them? is Advanced DOF noticeable or tessellation to be disabled??
