Last week Nvidia introduced its new G-Sync technology which is supposed to ensure that the refresh rate of the monitor is synchronised with the frames coming from the GPU.
Since early days, displays have had fixed refresh rates – typically 60 times a second (Hertz). But, due to the dynamic nature of video 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) eliminates tearing but causes increased latency and stutter as the GPU and monitor refresh at different rates.
G-SYNC eliminates this trade-off. It perfectly syncs the monitor to the GPU, regardless of frame rate, leading to uncompromised PC gaming experiences.
G-SYNC technology includes a G-SYNC module designed by NVIDIA and integrated into gaming monitors, as well as hardware and software incorporated into certain Kepler-based GPUs. (A full list of GPUs that support NVIDIA G-SYNC is available at here.
Many of the industry’s leading monitor manufacturers have already included G-SYNC technology in their product roadmaps for 2014. Among the first planning to roll out the technology are ASUS, BenQ, Philips and ViewSonic.
