- Have you tried setting MUI to simple refresh windows instead of smart

- This should have nothing to do with it. My system often has over 100
- tasks (including 6-10 MUI programs) running and it does not slow to a
- crawl.

- No doubt, MUI is designed for modern display resolutions, not 10 year
- old ones. It works much better on a graphics card.

- Because it would take too long to write, be too expensive to maintain,
- and be buggier. And it *is* pretty fast. The overhead of MUI is small
- compared to the time spent actually drawing graphics primitives,
- particularly if you have configured custom backgrounds and whatnot.
- Unfortunately, on AGA drawing graphics primitives is *incredibly*,
- *painfully* slow in high color modes, so this makes MUI slow as well.
- MUI is quite fast on my graphics card.

- No, the 060/50 is not about the same as a P100 for "raw processing
- power". Its more like half, by most standards of comparition. You can
- probably find an isolated instruction mix where it is comparable, but
- for real world CPU-bound tasks it is much slower.

-
- Sure. But will you _like_ it? I've got a PC that's much faster than my
- Amiga 4000/040/25, and has graphics that are much faster than my GVP
- Spectrum card. Yet I never use it. Go figure.

-
- If you can't afford a new Amiga, how about a used one? Pick up a used
- 3000/040, add a graphics card, and VMM, and you're set. It won't be as
- good of a games platform as the PC by any stretch. But that's not the
- only reason to look for a system.
