At 1000 sprites: PB 22 fps 68% cpu
BM 40 fps 100% cpu

at 2000 sprites: PB 13 fps 80% cpu
BM 20 fps 100% cpu

The opengl code does slaughter the BM code otherwise it seems that BM is better than PB on an old gforce 4 card.

For a new compare between PB 4.0 vs OpenGL we should use the same settings:

- same source (Maybe a littlbe bit more as one bitmap)
- same size on screen (no random size)
- same behavior on screen (moving, rotating...etc)

@pjay,
Are you interest on a comparison with your OpenGL version and the PB4.0 version?
