Overclock monitor = problem?

I recently overclocked my monitor from 60hz to 73hz. Everything feels smoother now but I have a problem. Minecraft only shows 73 fps, although I previously had 130 fps. This was of course not a coincidence so I set the monitor back to 60hz. Now Minecraft only showed me 60 fps. Only reinstalling Windows helped. Does anyone know why?

Detect in Minecraft VSync at graphics settings.
PC: A monitor with 73hz can only display 73FPS.
