I’ve noticed after switching to a 144hz monitor with g-sync that my framerate drops to like 1-2 during loading screens. I can maintain an average of 180+ in game but loading screens act odd. I’ve tried enabling VSYNC in game even though I have a g-sync monitor but that did nothing to solve the problem. And I guess now that there’s no dedicated full screen mode I don’t have that as an option to try.
I know its not a major issue, but just something that I’ve noticed that only happens with WoW. No other game I play has issues during loading screens.
