Well, technically vsync should slow down your frame rate. It holds back your monitor from refreshing until your GPU finishes processing the images on the entire screen.
With it disabled, the game will logically run at a higher refresh rate, but your GPU will process different sections of your monitor at different times making a "tear" across the screen.
