- Yes, but overtaking the blitter should be sure enough. Usually I tend
- to do as much as possible with the OS.

- Get a 50MHz 030 with 8MB fast (GJ unfortunately does not run on 4 MB)
- and watch GomJabbar/Matrix. You will see an 3xxx-poly object doing an average
- of 5 fps! There is also a duck running smoothly in 1*1 (ca. 20 fps).

- It's only factor 2 compared to ZIF/parallax...
