AI Summary

VSync, short for vertical synchronization, is a graphics setting that synchronizes a GPU’s output with a monitor’s refresh cycle to eliminate screen tearing, where fragments of two frames appear simultaneously. Enabling VSync can stabilize the frame rate by matching the game’s rendered frames per second to the display’s refresh rate, but it may also introduce other performance issues. A game’s frame rate measures how many frames the GPU produces each second, while a monitor’s refresh rate indicates how often it can show a new image. Ideally, these two rates align to provide efficient, responsive motion.
