The results from fumark benchmark
Hello.
I've noticed a performancedrop since mesa 10.1.4 (and also with 10.2.1 now). I
ran fumark_benchmark and unigine_valley. I append the results for fumark. I
don't know if it is kernel or mesa problem.
I use radeonsi.
Best regards!
Tom

Probably related to this:
http://cgit.freedesktop.org/mesa/mesa/commit/?h=10.1&id=1ba2298131924daf34b4504ba748a782c5189f48
Anisotropic filtering was broken in radeonsi, and that fixed it. Anisotropic
filtering has some overhead, which explains the slightly reduced performance.
This patch was applied to 10.1 and 10.2 branches as well as master.

Makes sense. Anisotropic filtering can indeed decrease performance a lot.
Closing.
