Do you want to disable Vsync, because it’s causing trouble? If so, here’s a short guide how you would disable it in Windows 7. On a sidenote, it’s also called vertical refresh. More after the break.
Well, since there are many graphic cards, I will only teach you how to disable Vsync for NVIDIA and ATI graphic cards. This should cover most PC’s, but obviously not all. If you have a different card, you’ll have to look into your manual.
Disable Vsync for ATI graphic cards (via CCC)

Disable Vsync for NVIDIA graphic cards (NCP)
1. Right-click on desktop, click on NVIDIA Control Panel
2. Uncollapse 3D Settings
3. Click on Manage 3D Settings
4. Scroll down to the bottom and click on the text Use the 3D application setting
5. From the dropdown select Force Vsync off (this will make sure that no applications can use Vsync and that it will be disabled even if a Vsync requires it)
Since the ATI and NVIDIA Control Panel tools are constantly updated this will be different in the future. If you can follow this tutorial step-by-step simply check out all the options in the Control Panel until you either find Vsync or Vertical Refresh.
