ForceVSync=(false, true)
This will force vsync, which is recommenced to prevent screen tearing.
VSyncSkipNumFrames
VSyncSkipNumFrames=(0, 1, 2, 3)
This tells the frame buffer to ignore the back buffer 0, 1, 2, or 3 contiguous cycles before grabbing a frame. This feature is mainly for users with high refresh rate monitors (> 60Hz) and should be set to '0' for most other users.
