Well, I just sucked down the OpenAL CVS (say, is there a way just to get
the Linux stuff without sucking down the Windows and Mac stuff as well?)
and compiled it with --enable-optimizations. I worked under the
assumption that openal.so is a renamed version of libopenal.so.0.0.6. If
that isn't the case, please correct me.
I backed up the original openal.so and copied the new one into
ut2003_demo/System. I benchmarked both botmatch-citadel and
botmatch-asbestos. With the new openal.so, I actually lost about a half
of a fps--probably not statistically significant. Even worse, though,
the music would sound like it is skipping.
My system is an Athlon XP 1800+, SoundBlaster Audigy with the latest
release open-source drivers, and a GeForce3 Ti200 with the latest NVIDIA
binary drivers.
