How do presentations work when loading?

[david.dickerson]

I'm working with large (40-60mb) presentation file sizes off of a CD.
How does PPT Viewer 2003 load a presentation? Does the entire
presentation get loaded into memory before running or does it operate
more like a buffer pulling what's needed as it's needed?

Sort of. As the presentation plays it builds a cache and the presentaion is
played from that. Very often you will see that playing the presentation a
second time results in the over all time of the presentation dropping.

So what would you expect the expectations to be Austin if I am running
a 60mb presentation off of CD? Would users with the minimum system
requirements for Viewer 2003 be able to successfully run the
presentation from the CD without too much difficulty?

In almost all cases yes.

Hi,

In addition to what Austin said, the viewer does not utilise hardware
acceleration. To me, that is a nuisance as it makes a huge difference on my
system. However, in fairness to the MS developers, it would be worse to have
it switched on and cause problems on machines that don't support it. But it
would be nice to have a switch in the batch file for it!
