I had heard that framerate should be capped to 3 frames below the max of the monitor.
Do I then go and disable in game vsync, and manually enable Vertical Sync through Nvidia “Manage 3D settings” on a game by game basis? Is on the one I should use or fast for the Vsync setting through NVIDIA control panel?
Or should I just stick with in game vsync?
On my displays (LG) you can open OSD (monitor’s own menu for brightness, contrast and all other settings) and it shows me some stats about current mode. It’s where Gsync shows up as on or off, alongside hdr, resolution, refresh rate etc.
May be a good place to check whether Gsync properly “engaged”.
