Did you use Steam games to get this working?
I can't get steam to load with the r9 290 and the open drivers.

I don't mean what Nine must do to catch up with Windowz. I mean if we assume that both give the same framerate in the future, what Nine can do to kill Windows. I assume that Calls-Compiler-State cost 30-50% of the CPU and the game's general code the other 50-70%. For the D3D part now, isn't possible to forcibly cut it from the main thread if the game uses only one thread for both and doesn't fill the GPU not on Windowz or on Nine? I speak about D3D threaded optimizations.
It's more 5% D3D calls, and 95% application, so with multithread you can get max 5%. (except some corner cases where it is more than 5%)

if game cpu limited: according to some old ATI docs, they gained only a few % going multithreaded, because most of the cpu usage is app side, and not driver side (we observe the same pattern with gallium nine).
For the games shown the fact it is not 100% is just the hw not being utilised an optimal way. Better resource placement, shader code generation, some performance bits, etc are needed to get maximum performance. This work has to be done in the gallium driver, not gallium nine.Last edited by artivision; 16 March 2016, 08:57 PM.

Unless you are planning on playing games, I guess the differences are not noticable for normal use? Libreoffice, web-browsing, etc?

Again, the breaking news here is not "only open source drivers forever", just "we're replacing Catalyst with hybrid stack and so current Catalyst is not going into 16.04".

The Tonga issue is a regression (incorrectly backported fix for Iceland support, breaking Tonga instead) in the upstream 4.4.4 kernel, fixed in 4.4.5.

At the end of the day for me, I will be looking at who has the best performing drivers (AMD/NVIDIA) come next videocard upgrade, if AMD are 'close' to NVIDIA performance then that's good enough for me. But atm they are around 1/3rd the speed of Nvidia OGL performance so I have allot of doubts about AMD's ability to catch up.
