I am experiencing screen tearing, yes I know the easy fix: "Turn on the vertical refresh." But the problem that I am having is that I am only experiencing it in one game. This game would be the original Mass Effect and the vertical refresh is already turned on. I also tried World of Warcraft, Counter Strike Global Offensive, League of Legends, Diablo III, Mass Effect 2 and 3. Nothing, no screen tearing what so ever in any of those games. So what could this possibly be caused by? How do I fix this?
