Guys, I have the Acer Predator XB271HU and I think that GSync stopped working since I installed my new 1080.
I see tearing in Battlefield and Titanfall. The screen light is always blue and I've set GSync to on, both in the control panel (Set up Gsync and Managed 3D settings under monitor tech).
I always turn off VSync in game options as well as I thought you were supposed to. Is something up? Should I do a clean GPU driver reinstall? Any way to test if it's working? I have the Pendulum demo but cannot tell if that's just advertising it or actually testing.
I used the 'GSync display' overlay in the CP but it was driving me mad as there's no toggle to turn it off.
Try disabling G-Sync entirely in the Nvidia Control Panel, apply the changes, switch it back on (make sure you choose to make it available in windowed mode), apply. Maksure that Manage 3D Settings > Monitor Technology is set to G-SYNC instead of ULMB or Fixed Refresh.
