Biggest thing in the patch? FPS - its up there. in full 1920x1200 extrme mode maxed out i have a tri-sli 480 rig hitting 120-140fps and the dual sli 580 's at 110 to 120 fps.
however, they get used so much that i have set temperature records for each that are a first both in this game.
never hit 80C during gaming before on the 480's and never hit 70C on the 580's before so they changed some stuff that made improvements. Keep it coming Crytek i hope this is just a baby step in your patch plans.
