SHOW does not operate well in modes
where only 256 colors display. At 256
colors, graphics look poor and
performance generally suffers as well.
On many machines, the best performance
is achieved at 16-bit color (thousands of
colors). This mode allows faster drawing
to the screen, and reasonably good quality.
On the newest machines, or for those who
want very good quality, 24-bit color
(millions of colors) is the best choice.
However, on older hardware that wasn't
built to be efficient in this mode, you may
notice a significant slowdown.
Choosing the display resolution will not
affect your performance significantly.
However, running presentations at a lower
resolution makes the show larger and
more visually appealing.
