G Sync Not Showing Up. G-Sync and FreeSync are similar, but different. You must be upset if you are unable to access.
Head to Display > Set up G-SYNC.
If you notice setup G-sync not showing up on your computer, it can be due to several reasons.
In a nutshell, it provides silky smooth, tear-free gaming by allowing the monitor and GPU to talk to each other. And technically windowed (even fullscreen windowed) applications cannot have screen tearing as they're first being composited by DWM before being shown on your monitor. G-sync enables you to experience maximum performance and the best graphics quality while playing games on your computer.
