You are supposed to use V-sync in the Nvidia control panel and cap your fps a few frames lower than your maximum refresh rate.Finally got the gsync indicator to pop up while playing so apparently its working, thing is I seem to get tears with it on, when I put vsync on(in the game) with the gsync its smooth as butter but your supposed to run gsync without vsync are you not?
You can cap it with RTSS or in game settings or just play at settings that don't go over.
