There is no way to turn hardware rendering off
from the IDL command line, to my knowledge. But
you can select software rendering on your draw
widget with the RENDERER=1 keyword.

Get a decent graphics card.

Hard to say. 95% of the craziness in object graphics
programs can be tied directly to the hardware rendering.
On programs I write that are suppose to run everywhere,
I always render in software. Surprisingly enough, for
a great many things, this is even faster than hardware!

If your object graphics program does things that *can*
be speeded up in hardware (lots of polygon rendering,
I think), then it may be worth it to you to upgrade
your graphics card. But just be sure your boss upgrades
hers as well, or your cool demo is likely to fall flat
on its face at the worst possible time. :-(

Cheers,

David
