Of course DPM was first priority. Optimization is the second and in my opinion feature parity is the third.
Ho-hum... Question, what is the bottle neck causing low FLOSS performance? Request, performance in 2D and 3D open vs. closed AMD-drivers in a FLOSS world.
Anyway, if you'll look at the gpu-limited applications in this benchmark - Unigine demos - you'll see that we are close. With other apps (mostly cpu-limited) higher cpu overhead of mesa/r600g probably shows itself.
this should give information enough to verify if the asic is droping to lower power states while in the test
The Linux catalyst driver is still supported and maintained as well as long as you are using a supported distro (kernel and xorg version). It's the same as on windows. The only difference is that windows doesn't change the kernel and display server as often as Linux distros do.But how does this driver compare to the still-maintained Catalyst Legacy driver for Windows 8?
