- I believe you, but I'll play devil's advocate for a moment... :-)

- Let's assume that today's 486/66 and Pentiums have at least
- two "units" of processor horsepower, twice as fast as the Amigas
- that had 1 "unit" of processing horsepower. Assuming the copper
- took no overhead, you had enough power on a 1-unit HP Amiga
- to render the next frame. Now you're on a processor that's
- probably twice as fast... you don't have enough time to
- render the lines and blit in that other 1+ unit of horsepower?
-
- I can think of at least one or two possibly opposing facts
- about PCs that might contradict this, as well as at least
- one or two counter-attacks to those...
