Vertical sync, more popularly known as VSync, synchronizes the refresh rate and frame rate of a monitor. GPU manufacturers developed this technology to solve screen tearing. Screen tearing happens when your GPU displays parts of multiple frames at once. As a result, displays may appear split along a horizontal line. When the frames per second don’t sync with the refresh rate of the GPU, tearing occurs.


Though screen tearing can happen anytime, it is most visible in vertical elements like buildings and trees during high-speed games with constant rate changes. Tearing breaks the viewer’s immersion and makes games look ugly.


VSync corrects this by limiting the graphic card’s refresh rate to frame rate, thus avoiding higher frames per second than the monitor’s capacity. It uses page flipping and double buffering to display frames after a refresh cycle finishes so that users don’t see tears.


I don't use it myself. I think with my refresh rate of 144 Hz, I don't see any difference, especially with fast paced games.
