Q: What have you announced?
A: NVIDIA has unveiled G-SYNC at a press event in Montreal on October 18th, 2013. A brand new display technology that provides stunning smoothness and ultra fast response for the next generation of gaming monitors, G-SYNC will redefine your gaming experience.
Q: How does G-Sync work?
A: Several years in the making, G-SYNC technology synchronizes the monitor’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 monitor, 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 monitor 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 is G-SYNC different than Adaptive V-SYNC?
A: Adaptive V-Sync is a solution to V-Sync’s issue of stuttering, but input lag issues still persist. NVIDIA G-SYNC solves both the stutter and input lag issue.
Q: What are the requirements for using G-SYNC?
A: System Requirements can be found here.
Q: What graphics cards support NVIDIA G-SYNC technology?
A: Any GeForce GTX 650 Ti BOOST or higher Kepler-based GPU.
Q: What operating systems support NVIDIA G-SYNC technology?
A: NVIDIA G-SYNC requires Microsoft Windows 7, 8 or 8.1.
Q: Does NVIDIA G-SYNC work with other competitive products?
A: NVIDIA G-SYNC only works with NVIDIA GPUs and G-SYNC enabled monitors.
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 games 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: What are the resolutions of G-SYNC monitors?
A: NVIDIA G-SYNC enabled monitors will be available in a variety of resolutions from 1920x1080, to 2560x1440 to 4Kx2K. The modded ASUS VG248QE monitors powered by NVIDIA G-SYNC has a max resolution of 1920x1080.
Q: Does G-SYNC work with FCAT?
A: FCAT requires a video capture card to catch the output graphics stream going to a monitor. Since G-SYNC is DP only and G-SYNC manipulates DP in new ways, it is very unlikely that existing capture cards will work. Fortunately, FRAPS is now an accurate reflection of the performance of a G-SYNC enabled system, and FRAPS output can be directly read by FCAT for comparative processing.
Q: What display companies are planning on introducing G-SYNC monitors?
A: Many of the industry’s leading monitor manufacturers have already included G-SYNC in their product roadmaps for 2014. Among the first planning to roll out the technology are Acer, AOC, ASUS, BenQ and Phillips.
