On the Amiga, scrolling, sprites and stuff like that was done by special
hardware (blitter chip etc.). Thats why it was all so smooth. On a IBM
using Mode-X graphics, scrolling should be smooth as well, even if running
in a dos-box (at least the Allegro V2.2 demos run smooth on my win95 p133).
Generally you can't expect the performance of hardware graphics chips from
that slow VGA card, but on the other hand, you're hardly restricted in the
size/number of sprites etc. when using a software solution as Mode-X sprite
routines.
