Have you looked at Dalektron (www.dalektron.org)?
The bouncing balls example works by painting the sprites onto a double
buffered bitmap and then blitting this onto a window canvas. Since the
Windows GDI was never intended to produce fast animation this can
result in rather poor frame rates (although much will depend on the PC
speed and graphics card). This is the reason why MS created DirectX so
it would seem sensible to use that if you want better animation in
Dolphin.
