G-SYNC General FAQ
Q: How does G-SYNC work?
A: Several years in the making, G-SYNC technology synchronizes the display’s refresh to the GPU’s render rate, so images display the moment they’re rendered. The result: Scenes appear instantly. Objects are sharper. Game play is smoother.
Since their earliest days, displays have had fixed refresh rates – typically 60 times a second (Hertz). But due to the dynamic nature of PC games, GPUs render frames at varying rates. As the GPU seeks to synchronize with the display, persistent tearing occurs. Turning on V-SYNC (or Vertical-SYNC) can eliminate tearing but causes increased latency and stutter.
G-SYNC eliminates this tradeoff, perfectly syncing the display to the GPU, regardless of frame rate, leading to uncompromised PC gaming experiences.
Q: How much performance gain can I expect to see with G-SYNC technology?
A: NVIDIA G-SYNC ensures that every frame rendered by the GPU is displayed (up to the max refresh rate of the monitor). It does not increase the rate at which the GPU renders a frame.
Q: What are the benefits of G-SYNC over V-SYNC?
A: With V-Sync, the GPU and display are synchronized to the vertical blanking interval where the GPU sends rendered frames to the display on a fixed cadence (60 times per second at 60Hz display refresh). There are two issues for gamers when using V-Sync:
- Stuttering since the GPU might render frames at rates other than once every 1/60 sec
- Input response is fixed and limited to 1/60 sec
G-SYNC addresses these issues since the display accepts frames as soon as the GPU has rendered them which delivers smoother game play and maximizes input response.
Q: How does NVIDIA G-SYNC work with SLI?
A: The NVIDA GPU connected to the display manages G-SYNC. SLI GPU setups work seamlessly with G-SYNC displays.
Q: Does NVIDIA G-SYNC work for all games?
A: NVIDIA G-SYNC works with all games. However, we have found some games that do not behave well and for those, we recommend that users take advantage of our control panel’s ability to disable G-SYNC per game. Games that NVIDIA discovers that have trouble with G-SYNC will be disabled by default in our driver.
Q: How does G-SYNC impact game input latency?
A: Unlike V-SYNC, G-SYNC has no impact on input latency, which makes it perfect for first-person shooter games and competitive eSports.
