Yes, I understood that part in your first mail. My point was that while the
implementation of native quartz MAY be more efficient, using DirectDraw in
Wine is not faster than using GDI directly per se. That doesn't mean that
native can't be faster than builtin, but that would be because of a better
implementation, not because it uses 2D ddraw. Direct3D, on the other hand,
would be hw accelerated, and thus faster. Sorry that I didn't make this
clear.
