Reduce frame rate without v-sync or screen tearing
Reduce frame rate without v-sync or screen tearing
Setting a fixed framerate behaves similarly to VSync. I think Nvidia lets you choose whether to use VSync or switch to VSync when the frame rate exceeds your monitor's refresh limit (the same applies for AMD and Freesync). For me, Bioshock Infinite was the most tearing game I've ever experienced (especially on my old 60Hz display). EDIT: Turn on VSync in the game. It will continue using GSync but change to VSync when the frame rate gets too high. The same applies for Freesync users on AMD.
You're right to question this! Enabling V-sync and G-sync are related but distinct features. While they both aim to improve smoothness, enabling V-sync doesn't automatically disable G-sync. They can work together for better performance, but you need to understand their individual settings.
Turning off/disabling vsync in the game doesn't stop G-SYNC, but it informs the Nvidia driver how to handle frame rates higher than what the GPU or monitor can manage. If you activate vsync in the game, G-SYNC remains functional, though if your FPS exceeds 144, it will block the app until the display is ready.
Vsync should adapt to your screen's refresh speed. Some titles might behave differently, but this is the intended behavior. Regarding Gsync, I lack information since I don't own a Gsync display. However, it seems likely many older games run at higher speeds than 144 FPS, so they probably use vsync or similar frame rate controls.
You're facing a common issue when pushing high refresh rates like 144Hz. It sounds like your setup is working well overall, but there are a few factors at play. The GTX 780 may have limitations with G-Sync support at higher frame rates, and the PG279Q module might not be handling it smoothly. Also, even with triple buffering and max rendered frames enabled, some games can still cause tearing if the monitor or driver isn't fully optimized for those settings. Try adjusting your game's resolution scaling or checking if the monitor supports G-Sync at 144Hz.
