...I've been following this problem with Xracer on the Xracer list --
it's not texture related there, it's display list related. What their
code is doing is creating 2000+ individual, pretransformed display
lists for each segment of track, and apparently under MesaCVS it's
causing huge memory usage such that it crashes on most setups (mine
included -- it uses all 256mb ram + 256mb swap and dies). I mentioned
on the list that they ought to only make display lists for unique track
segments and then glTranslate()/glRotate() them into position because
there's little/no performance boost from generating 2000 unique display
lists that each only get called once (please correct me if I'm wrong
there).
The last impression I got before the thread ended was that the main
programmer(s) on Xracer were resistant to making this change because of
increased code complexity (right now they just render all display lists
in order with no transforms in between), though that might change if
they reorganize the rendering engine in the future.
I can verify that I couldn't get Tux_aqfh to work some months back when
I gave it a shot, but I haven't tried any of the recent releases.
