Rapid motion does change the way triangulation is done. In fact , the
antialising settings are no longer controling the antialiasing, but the
tesselation. Try rendering a simple sphere with rapid motion scanline
(no motion blur) with AA set to -5, -2. You will see the effect right
there.
Maybe you already knew all this and you are talking about something else?
