i use TFT Central's ICC profile. I also use their calibrated settings except i have brightness turned down to 22 (instead of their 27), but that'll depend on your lighting conditions. i have Trace Free set to 40.i game fine on this monitor, but i'm getting restless and i'm tempted to try out 144hz and/or G-Sync soon.
tip for anyone playing the beta, when you equip optics on a gun click "medium range" or "close range" at the top of the optics menu. it will bring up an option to swap from one to the other. for instance, you can equip the MG36 with close range (1X) optics. i didn't know this.
edit: also sniper rifles with close range optics is fun
