I have been having problems with black lines going across my screen in video games when I move. When I move up and down there are horizontal lines on my screen and when I move left to right there are vertical lines on the screen. The only games I've really noticed this in is Arma 2 and Fallout 3. I uninstalled all my drivers, but for some reason everything looked normal on my homescreen, not like intel graphics. I installed the 13.2 beta drivers and it looks the same. Should I RMA the card or am I doing something wrong? Oh and my specific 7970 is the Sapphire vapor-x GHz.
