Nvidia G-Sync in action

First look at Nvidia's new GPU monitor synchronisation technology

By


Introduction

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. On Friday we had the opportunity to see G-Sync in action at Nvidia's office outside of London. We left quite impressed.


Most monitors have a refresh rate of 60 Hz, which means that 60 frames are displayed per second. There are of course gaming monitors with refresh rates of 120 Hz or even 144 Hz. Graphics cards are much less consistent when it comes to frames. With G-Sync, finished frames are transmitted directly to the monitor and also displayed directly. Nvidia claims that artefacts such as stuttering and screen tearing will no longer occur with G-Sync. 

Nvidia’s Tom Petersen demonstrated G-Sync with two ASUS VG248QE monitors, one with G-Sync enabled and one without. Both screens had a refresh rate of 60 Hz and were connected to identical PCs equipped with a GeForce GTX 650 Ti Boost. The 650 Ti Boost is definitely not one of Nvidia’s fastest cards, but their intention was to show that the technology works very well with PCs that aren't powerful enough to achieve extremely high frame rates.
