Hi I have a problem when I have G-Sync enabled in games like Hearts Of Iron 3, and shogun 2, starcraft 2 (Works fine in Battlefield 4 and metro last light) There is a really weird sort of lag when something is loading. Like for example in Starcraft 2 when im loading something either a match or the options menu, it gets really laggy and the screen flickers. With G-Sync off this doesn't happen. It basically seems like whenever something loads it makes something go ham. I tried recording the problem but it doesn't show in the video. I'll try to record a video of it with a camera if needed.

I'm on driver 340.52 (GTX 690 no overclock)
