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.
