Hello,
I'm not sure if I should have posted this to the users list instead, sorry
if I should have. Since about three weeks ago, the latest FlightGear CVS has
been giving me abnormally low framerates (3-4 fps), much lower than what I
used to get. It doesn't seem to depend on what options I run FG with, except
for one thing: the Concorde is immune to this problem. I can get about 30
fps with Concorde, but every other aircraft I've tried has the same problem.
I get three error messages, but I've been getting these for a few months and
I haven't had problems before:

> libGL warning: 3D driver claims to not support visual 0x4b
> Warning: detected OpenGL error 'invalid enumerant' after
> RenderBin::draw(,)
> Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,)

I'm using OSG version 2.0 on Debian Etch,  and my graphics card is a Radeon
9250 using the open-source ati drivers. Any ideas about what might be wrong?
Thanks,
Will
