Justin, as far as I know Voodoo drivers have had this option for a few
years now (I haven't been able to find a way to do this on Matrox
cards). It is driver dependent. NVidia's detonator drivers allow you to
go into their advanced options; Additional Properties; to turn this on
or off (at least it works for my GeForce 256).
The problem with turning off VSync is that you then allow a new frame to
begin being painted in mid screen and this can cause some strange
graphic artifacts.
