Sets whether vertical sync should be turned on or off. This is the preferred method of limiting the frame rate as it will link the frame rate to the monitor refresh rate and avoid tearing or stuttering. Using this command with mode 1 will override any currently set refresh rate from SetSyncRate, otherwise these two commands would fight each other for control of the frame rate, instead AppGameKit will use the VSync refresh rate which is typically 60 frames per second.
Thats what is in the docs for the VSync command, have you tried you program using just the SetSyncRate( 0, 0 ) as I have never used the SetVSync() when doing this and it has always worked.
