Thanks, the AO was a big reason why it was such bad lag lol, but even with it off its impossible to stay in the high 50s to 60s fps with everything else on max. This is definitely one of the toughest games my computer struggled to run, even without any AA the gtx 580 was running 100% which is pretty funny considering crysis 2 with dx11 patch doesn't even make the gtx 580 run close to 100% at all.
