what is adaptive sync

Adaptive Sync is a technology that dynamically syncs the monitors refresh rate to the GPU's frame rate to eliminate screen tearing and reduce game stuttering. It was created to solve several problems that can seriously degrade the experience of using a PC, such as screen tearing and lag. Adaptive Sync adjusts the display’s refresh rate to match the GPU’s outputting frames on the fly, displaying every single frame as soon as possible to prevent input lag and not repeated, thus avoiding game stuttering and screen tearing. Adaptive Sync is an open standard defined by VESA, which any company can use to enable adaptive sync between a device and display. It is used not only by AMD but also by Nvidia. Adaptive Sync can also be used to enable seamless video playback at various framerates, whether from 23.98 to 60 fps, changing the monitor’s refresh rate to match with the framerate of the video content, thus banishing video stutters and even reducing power consumption. G-Sync and G-Sync Ultimate displays use proprietary Nvidia G-Sync modules that only sync with Nvidia graphics cards, while most AMD FreeSync displays can sync with Nvidia graphics hardware, and most G-Sync Compatible displays can sync with AMD graphics hardware, although this is unofficial.
