Im getting weird texture flicker patterns on both Starcraft 2 and Heroes of the Storm. Also, FPS is super inconsistent on GTA 5. Running the 7990 with an i7 3770K. It's liquid cooled, no way it's overheating.
I have installed the latest drivers for the card...I saw a slight bump when I upgraded to the 14.502.1014.1001 AMD CCC driver in GTA V, but the texture flicked problem in the other games has been consistent across the board on driver versions. The Blizzard FPS is good though...just GTA5 is jerkin even at 50% throttle in the game.
