On PCs you could easily configure the Vertical Sync setting from NVidia control panel, how can you enable/disable vertical sync in OS X?

In OSX, Veritical Sync is called Beam Sync

Running the command sudo defaults write /Library/Preferences/ Compositor -dict deferredUpdates 0 should do it for you, but you may need to reboot. Replace the 0 with 1 to re-enable.

You should also be able to do this by downloading this prefpane and looking under "System". Another way is to use Quartz Debug to disable it, but it seems like that has become harder to run on Lion & ML.

I love Mac, but life would be so much easier if they'd use standard terminology. Reminds me of when IBM insisted on calling pixels "PELs." – David Lively Oct 23 '13 at 23:42
