What is vsync in minecraft?

Vsync, short for vertical synchronization, is a feature in Minecraft that helps prevent screen tearing by synchronizing the game's frame rate with the refresh rate of your monitor. When vsync is enabled, the game limits the frame rate to the maximum refresh rate of your monitor, usually 60Hz or 120Hz. This can help create a smoother and more visually pleasing gaming experience.

However, enabling vsync can also introduce some input lag, as the game may need to wait for the monitor's refresh cycle to display a new frame. Some players may prefer to disable vsync to reduce input lag, but this can also lead to screen tearing, where two or more frames are displayed on the screen at the same time.

In Minecraft, you can enable or disable vsync in the game settings menu. The option may be found under "Video Settings" or "Graphics Settings," depending on the version of Minecraft you are playing. Players can experiment with different settings to find the balance between visual quality, smoothness, and input lag that works best for them.
