Anyone else getting lag/stuttering after alt-tabbing out and then back into the game?
I have smooth continuous game play to start with but more often than not I get stuttering (or possibly lag) as soon as I've alt-tabbed out of the game to minimise the window size and then clicked back on the game window to return to full screen.
I've tried all the suggested solutions e.g. disabling HT, disabling various settings in game, all latest drivers, and I've even gone back to a vanilla build of Windows 7 to no avail.
I'm running a H55 based board, i3 @ 3.7Ghz, 5850, and 8GB DDR3...
