I've noticed that half the time when I play ArmA 2, my GPU (Sapphire 7950OC) doesn't even pick it up, my GPU usage sits at 0%, I get less than 20 FPS, and I'm forced to keep closing and opening the game until my GPU actually 'engages'. Has anyone else run into this problem?
I also have a strange problem the moment I actually start playing, I get an odd flashing, like someone is turning the brightness up and down, or the HDR is pulsing. It eventually goes away, sometimes in seconds, sometimes it takes several minutes, and once it stops, I'm good until the next time I launch the game. I've tried every different combination of video settings but nothing seems to help.
Also tried the [shift] - FLUSH thing, that doesn't help either.
My specs:
Windows 7 Ultimate
i7 920 3.2GHz (also tried at stock, all problems persist. HT disabled.)
Sapphire 7950 with 12.4 (newest) drivers
6GB of RAM
