Well, considering that FlightGear is doing easily 2-10x as much
work per frame as glxgears, I'd say that those numbers are
relatively unsurprising.

The last time I was using a 32Mb card (Radeon Mobility 7500) was
about a year ago.  At that time, a big chunk of the performance
hit was due to texture swapping.  FlightGear's default textures
didn't quite fit into the card.  I wrote a quick perl script to
iterate through all the .rgb files in the base package and
use "mogrify" to resize them to at most 256x256.  This got a
pretty good speedup, if I remember correctly.

But probably the best solution would be to invest $50 or so in a
cheap, modern video card (I see a Geforce FX 5200 128MB listed on
pricewatch for $46, for instance).  The machine you are using is
5-year-old technology, and isn't very representative of what the
FlightGear developers are using.  There's no reason in principle
that it can't be supported, but past a certain point developing
for testing on older hardware takes more time than is available.
