AMD FreeSync is an adaptive synchronization technology designed to reduce screen tearing and stuttering in games by allowing a compatible monitor to dynamically adjust its refresh rate to match the frame rate output by the graphics card. This results in smoother gameplay and improved visual performance, particularly in fast-paced games. Nvidia’s equivalent is called G-Sync, and you may be wondering whether FreeSync is compatible with Nvidia cards, and the short answer is yes, though there are caveats to that.
