A Mesa developer has put out a set of 42 patches to help improve Dawn of War III performance on Linux using Mesa. It focuses on the use of KHR_no_error to save some more CPU time.
The patches landed earlier today in Mesa-dev, so they are not yet accepted into Mesa-git. You can find the start of them here. Below is what Mesa developer Samuel said:
*Piglit is a set of automated testing tools for OpenGL
The KHR_no_error extension, from my understanding, removes certain error checking to allow for more performance.
Fantastic to see performance continue to be worked on! Article taken from GamingOnLinux.com.

I didn't do any benchmarks, but this should save few CPU time here and there.
