A really bad spelling of "v-synchronizing"...

Vertical synchronization or V-Sync

Syncs your framerate to your refresh, or half, basically it keeps the screen from tearing.

When your display driver is requested to be V-Synch'ed, only full frames will be displayed to the screen, otherwise, even partial frames will be sent to the screen.

Sending partial frames causes some 'tearing' to occur, however, it will help the smoothness of a game to show all frames partial or full.

For example, Oblivion is a very graphically demanding game, enabling V-synch may put out an average 20 frames per second, but they will all be complete, incomplete frames will be dropped in favor of full ones. However disabling V-synch will bring your fps up, to 30-35 maybe, but some frames may be patchworks of 2 frames split somewhere along a scanline, causing 'tearing'.

I am explaining this from experience, not actual hard information. On games where you've got no trouble keeping FPS up, enable v-synch, on games that are taxing your GPU too much, disable it. Thats my rule of thumb for that.
