I currently have a Raedon 280x XFX graphics card. Normally I have 200-300 fps, but the frame-rate drops to like 80 or less when the game becomes more intensive. When I first built the computer even the most intensive parts of any game I played didn't drop below 200, but now they do. I checked my graphics card drivers, uninstalled them, and reinstalled them, but the problem still exists. Any suggestions?
