Just got a copy of the game recently. But after some traning missions, I have found I could not enable AA, AF or V-sync for the game. The graphics were still jagged and the screen was still torn even I hadenable AA, AF and V-sync in the nHancer. And with a 4 Ghz i7 920, my fps was still at a low level with affinity set for 8 cores. The in-games graphics settings are all maxed out except the mirrors disabled. Resolution is set at 1280x1024. With these settings, the FPS is only around 30 in the cockpit in the hover control training mission. And The video card driver is up to date. Even with maxed out settings in ArmA 2, I can get a fps higher than this.
