Hi guys

I need help.

in any games, I can get gsync working only in window mode. When i change to fullscreen or to borderless, gsync is gone.

Any clues guys? :( Thanks

Do fps remains same when switching from windowed to other modes?

Make sure G-Sync is enabled for both "Fullscreen and Windowed mode" in the Nvidia Control Panel. Also, Some system overlays or multi-monitor setups can interfere with G-Sync in fullscreen

Hi, yes I have set it for both.

I have multi monitor setup.

I just find out that in War Thunder, in DX11 mode I have this issue, but in DX12 its working - gsync works in fullscreen and in borderless.

yes fps remains same all the time. Just frequency become to be dynamic based on FPS and I see g-sync mark in top right corner.
