I''ve noticed that my graphics card has settings in the control panel vsync. Force off. On by default. Off by default. My question is from the perspective of the application, is there a way to ensure that even if the setting is off or off by default, is there a way to sync to vertical retrace. Tearing sucks when you''re drawing faster than your vertical retrace anyway. -- - Aaron
