Matt's is a special case of the general principle, don't work in smaller
chunks than you have to.  For example, if you are moving a sprite around
the screen at high speed, don't move it a pixel at a time.  Rather, work
out how far it will go in one complete screen frame (1/70 sec mono, 1/50
or 1/60 second in colour) and then move it that many pixels in one jump,
synchronized with the VSYNC.  You can get a lot of speedup that way in
many cases.

Of course, you have to work out whether you are talking to a mono or colour
monitor, and if colour, at what frequency, but you can get the OS to tell
you all that.
