- Well, there's a easy way of getting sure 50 (or 60) fps without turning off
- the interrupts. Use them yourself. Make them high priority ones, and nothing
- can stop you from having all the time you want, while the system is running
- (well, would be if there's time) in background. If you don't mess with the
- copperlists yourself, but use Views for that, you can even switch back and
- forth applications... Now all this is unnecessary on a A500, as all the time
- is probably used anyway, but what if you have a 25MHz 68030? A lot of time
- is left unused, and could be used your something else, provided you don't
- do the blitter waiting in busy loops... There are ways around that too.
