Question xb271hu bmiprz G-SYNC ISSUE

[Lordslav]

Hello so I have an issue with g-sync I couldnt get it working and I was playing with it couple hours and I got it working only when im in windowed mode and it doesnt work in fullscreen at all any idea what could be wrong? Im running it with displayport on gtx 1080
I also tried running it in the nvidia pendulum and it works fine in windowed mode but not in fullscreen im not getting the 'G-SYNC ON' notification in the left top corner and I cant even select the 'G-SYNC' option in fullscreen

I've found that tends to be a game specific problem. Some titles have to be run in full screen windowed mode to get G-sync to work. CryEngine comes to mind.

Pretty much been my default selection since I got an PG279Q.

Well that would make sense but I tried running nvidia pendulum which is a g-sync benchmark and I cant even select the g-sync option if im in fullscreen
