It does sync. your grapics card with the Hz (refresh) rate of the monitor.
If "on" it can make the visual "smoother" , and there won't be the tearing edges on the screen if you turn the camera fast from left to right.
Test it! Turn it on and play the game and move the camera fast.
And then turn it off and do the same!
You will "see" what it does!
Turn it off... we all do!
