Does the vsync option in the control panel produce less input lag than using vsync in MAME?

Yeah, there are many reasons to use Direct3D. For example if you want to use bezel artwork, then the DirectDraw function will first resize the artwork how it would look like on a screen with minimum resolution (i.e. where the game image wouldn't need to be stretched) and then it enlarges this small image to the actual size. Which results in a low quality artwork even though the actual artwork had the correct resolution. Also, scanlines are one line per pixel row of the screen in Direct3D and one line per pixel row of the game's raw image in DirectDraw.
Using Direct3D in windowed mode worked fine on my system. Of course, you have the window border and the visible desktop with that.
