--- Comment #7 from Stefan Dösinger stefandoesinger@gmx.at 2011-09-03 14:51:02 PDT --- I installed libtxc_dxtn.so, this improved ut2004 performance. I now get 15-20 fps in most non-fighting rendering situations. That's better, but still 1/3rd of what Windows gets.

Interestingly etracer is also faster, and I don't think this game uses s3tc textures. "Who says penguins can't fly" renders at 60 fps most of the time in the canyon, with very rare drops to 30 fps for a second or two.
