I cannot play Amnesia Dark Descent at all. Both eyes get flashing flickering of the game and the frame rates is so low it would be less than 1 frame per second. Im running win 10 64 bit. AMD fx-8350 Black edition and an R9 390x video card. Quake 2 does the exact same thing. I have tried many settings to no avail. Games like Skyrim and fallout 4 run just fine. It seems to be a possible issue with Open GL not really sure. Any help would be greatly appreciated.
