The 3D textures performance seems to have gone down severely. By about a third.
I used code from here for testing. The FPS has gone down by about third
If I understood correctly what happened recently pretty much every new advancement in r600 requires a more recent kernel (not just the color tiling) because of massive drm changes so these comparisons are not quite as they should have been made.
For a better understanding of what has changed and how much the tests should be done with a more recent if not multiple kernel versions both with and without KMS enabled.
I noticed there was promise at the end of the article for more benchmarks with newer kernel, I hope they do multiple kernel versions if not for other reason than just to spot any possible drm regressions in these newer kernels.
Can it handle Blender3D?
I'm going to need the S3TC support from Mesa's R300 driver(s) before the R600 drivers become a viable alternative.
Some extra benchmarks you can throw in are:
Speed-dreams, which is a fork from Torcs.
Torcs was about writing racing simulations and AI drivers, Speed-Dreams is aiming at making a more fun game for a wider audience.
This one tries to make more use of graphics and is designed for more of the 'faster and the furiouser' crowd.
And then also flightgear:
These ID-engine-based-only FPS benchmark artiles are killing me. This will at least get some more variation in the benchmarks with engines from entirely different code bases.
I am sure that if you work with the developers of those games a bit they can help you get a reproducible scripted game session. Tell them it will help find problems in OpenGL drivers before it hits their users and will help provide more exposure for their projects.
