Should I Have Gsync On?
G-Sync is usually worth turning on if you have a compatible Nvidia GPU and monitor and your games run at variable or lower frame rates, because it reduces tearing and stutter. It is less beneficial if you are a competitive player sustaining very high frame rates and prioritizing the lowest input lag, or if your monitor has a narrow or flicker-prone variable-refresh range. Weigh your hardware, the games you play, and your tolerance for latency versus smoothness before deciding.
