Hey guys. I couldn't find a thread addressing my specific issue, so I thought I'd start one. My in-game performance drops considerably when I fullscreen my game. I have disabled the Steam overlay, and tried multiple graphics configurations to no effect. Setting fullscreen in the game settings and Alt+Enter both slow the game down. My Setup: Windows 7 64-bit i7-2500k GTX 580 8GB RAM I'm away from my computer, but I'll provide some more information if required when I get back. Has anyone else had this issue, or know how to correct it? Thanks.
Please upload your DxDiag.txt. Also can you give some FPS (press Ctrl+P to toggle FPS view) comparison? E.g with fullscreen and without it.
