Its an aspect of project butter....
Vsync matches your monitors refresh rate/frequency, with a 3D applications frame rate.
In other words, It doesn't let your frame rate go above your monitirs refresh rate.
85 Hz. = 85 FPS
100 Hz. = 100 FPS
and so on.

It is, but google now added, that the logic of the application (when stuff happens) is also synchronized to it, which might increase performance of apps while lowering unnecessary processor usage
