G-Sync is Nvidia monitor or display technology to help eliminate judder, stutter, tearing whilst gaming, and syncs to GPU to the monitor refresh rate. Of course, for our tips to work, you will need a Nvidia graphics card and a G-sync, G-sync compatible, or G-sync ultimate display. Now, this guide isn’t to explain what G-sync is, but to give you a set of “must do’s” to get the most out of your G-sync experience.
In your Nvidia control panel, locate the G-sync channel on the left. Select enable G-sync/G-sync compatible for full-screen mode.
In your “manage 3D settings”, near the bottom, enable V-sync (on at the global level). These work in tandem very well.
Run your games in full-screen mode, or exclusive full-screen. You can make sure G-sync is working via the Nvidia control panel (display > show indicator for G-sync).
Disable any and all vertical sync settings in-game. This includes any double or triple buffering.
Limit your FPS in-game (preferred) or via a 3rd party program (RTSS is fantastic) to 3 frames BELOW your maximum refresh rate (ex: 60hz = 57FPS).
Easy enough, right? Many people assume that just with G-sync active, they are getting peak performance for their investment. Sadly, you need a little elbow grease to fine tune it all and get a butter smooth presentation.
