Description: The VSync rate, or vertical synchronization, refers to the frequency at which frames generated by the graphics card are synchronized with the refresh rate of the monitor, typically measured in hertz (Hz). This technology is implemented to prevent screen tearing, a phenomenon that occurs when the graphics card sends new frames to the screen while it is still updating the previous image. By synchronizing the output of the graphics card with the monitor’s refresh rate, VSync ensures that each frame is fully displayed before the next one is presented, resulting in a smoother and more coherent visual experience. However, enabling VSync can introduce input lag and, in some cases, may limit overall game performance, especially if the frame rate generated by the GPU exceeds the monitor’s refresh rate. Therefore, gamers and graphics professionals must carefully consider the use of VSync based on their specific needs and available hardware.
