questions on display and performance...

[Rich]

When I go to control
panel>display>settings>advanced>performance what
does "accelerator function" do? and, what does it mean
when I move the bar to the max when it says "use if your
computer does not experience any problems"?? What kind of
problems is it talking about?

And another question. I have a nVidia 100/200 video card.
on its properties it says "refresh rate." What does the
refresh rate do? Is the refresh rate commonly associated
with problems one can experience during full-screen
programs?

Before I got the video card, I used to be able to run full-
screen programs. However, now, as the screen adjusts to
the program's settings, one of those "illegal operation"
screens pop up, and my computer freezes. How can I solve
this? It happens with all of my programs.

Thanks in advance,
Rich

The more acceleration that is selected then the more of the processing work
is shifted from the PC to the video card. Since not all video cards are
fully compatible with Windows then full acceleration sometimes produces odd
effects, like windows failing to refresh or images left behind on screen as
windows are moved or closed. You will quickly notice any problems associated
with having too much acceleration.

Refresh rate is the number of times per second that a fresh image is sent to
the monitor. Generally, you should select the highest rate that your
monitor supports, but any rate above where you can detect flickering is OK
in practice. Whether or not the refresh rate is associated with problems
using full screen mode depends on what those problems are, but I would think
it is unlikely.
