Hey everybody, recently I've been noticing that my 7990's performance seems to be a little problematic. Mostly in games it seems to be fine but for some reason it seems to have the worst time whenever I try to play DayZ. My FPS is always below 60 and seems to drop below 30 very often. I have no clue why this would be happening as everything I've read has said that a 7990 should be able to tear through this game.

My specs are:
XFX Radeon HD 7990
AMD FX-9590 @ 4.7GHz
16GB DDR3-1866 G.SKILL Ripjaws X
AZZA Titan 1000W - 80 PLUS Bronze PSU
Gigabyte GA-990FXA-UD3 Motherboard

Any help would be much appreciated! :)
