Hello, are you using multiple displays and ‘windowed fullscreen’ mode? If so, try the ‘Fullscreen’ mode and see if the issue persists. Please let me know if this works or doesn’t. Thanks! /Mark
Try turning off your overclocks. It likely is an overclock issue. Almost all the people I have seen complain have had overclocks over 4Ghz. I know that has caused issues before in a few games, it just is uncommon.
