The Grinch That Stole The Radeon Gallium3D Performance?

Just export LIBGL_DRIVERS_PATH=/path/to/mesa-source/lib and then export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$LIBGL_DRIVERS_PA TH. There's no need for LD_PRELOAD. Then, you don't have to 'make install'.

It's more likely that the developers implemented a new feature, application runtime logic saw the new feature and used it, but for that particular application/card/driver combination using the new feature is actually slower than running without the feature. Game developers do often put heuristics in which help to choose the right code paths depending on GPU/CPU/driver but they tend to be backward looking and have trouble dealing with a driver that is constantly evolving.

I notice you didn't check out r600g, which does support all the RadeonHD models.
Also worth a mention but not really a big issue is r100 and r200, but those cards are so old that I doubt anyone using them is running anything too stressful on the GPU.

Kudos Michael.

I'm not sure if both of those are necessary - i think it's just one of them.
LD_LIBRARY_PATH=/path/to/mesa/lib is needed for mesa's libGL.so, however usually your system stock libGL.so is sufficient.
