Enable VSync

Question

Hello Boys and Girls, I am coding an award winning ultra mega cool game. First, I noticed some flickering, so i did all this anti-flickering stuff, like .SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.DoubleBuffer,true); this works, but now i have faster movements and I see some flicker. Not much, but it is there. Could it be, that a disabled vsync is responsible for that? If yes, how can i enable it?
