Does VSync increase input lag?

There's no tearing or over-processing to fix, so the only effect VSync will have is potentially worsening your frame rate and causing input lag. In this case, it's best to keep it off. When used correctly, VSync can help smooth out issues and keep your graphics processor from running red-hot.
