Nvidia has developed new technology to improve visual performance in video games: G-Sync, a module for computer monitors that "brings big benefits for gamers," according to a blog post from the company.
G-Sync is designed to attack a key hurdle in display technology: the syncing between a graphics card's frame-rendering rate and a monitor's refresh rate, both of which are usually set to 60 Hz. That fixed refresh rate forces users to play with vertical synchronization (VSync) on, which causes latency and image stuttering, or with VSync off, which leads to screen tearing.
Instead of syncing a GPU to a monitor, G-Sync does it the other way around: The monitor only refreshes after the GPU has finished rendering a frame. According to Nvidia, keeping the monitor in sync with the GPU reduces screen tearing, stuttering and input lag.
G-Sync takes the form of a module that can be built into a monitor or installed onto an existing display, and the chip works with the hardware and software in many GeForce GTX cards — a GeForce GTX 650 Ti Boost or better. The first monitors with G-Sync will be available later this year: Nvidia is sending the modules to professional modders who will install them into Asus VG248QE monitors, and those G-Sync-equipped displays will cost a bit more than the standard ones. Monitors with G-Sync modules pre-installed by display manufacturers will start to be available next year.
