    I think that day has already passed.

      This is a good sign, hopefully AMD will be able to put more and more effort into improving their Gallium drivers and unambiguously reach parity soon. I'm planning a new build in early 2017 and I'm seriously eying AMD since I'm fed up with proprietary drivers.

      Have you done any Polaris Windows vs. Gallium/Pro benchmarks? That would be useful you're up for it.
      I was thinking the same regarding Windows comparisons. And add the 290 (hopefully the regression is taken care of soon).

        Yes, will be doing some next week or so now that I got these Linux numbers done, at least for tests where I have compatible windows test profile.

          I just tried duplicating these results using phoronix-test-suite. For some reason, the AMDGPU-PRO driver always performs much worse for me on my new AMD R9 Fury on Ubuntu 16.04 when comparing my results to the ones Michael are getting (around ~25-30 percent lower). Is there something that I may be missing that I should be aware of or is my GPU simply being bottlenecked by my i5-2500k CPU?

            Composition, governor... i can suggest to check as common diff . And to run some unigine benchmark, so if you still has there that much lower results then it is your CPU.

              Thanks for the suggestion. I can't seem to find anything related to governor settings for the GPU though. Are You referring to the governor for the CPU?

                Michael Can you make a frametime graph for csgo? Or maybe just try playing an arms race bot game or so? The average FPS seem okay, but ingame the FPS vary a lot and drop pretty low. For example: https://i.imgur.com/Jv6MF1n.png
                Yes, that is a drop to 0 fps for ~0.5-1 second in there. They randomly happen. Makes it 100% unfit for playing competitively.

                  I think it's caused by shader compiles. The same goes for Left 4 Dead and it's really annoying. If they do the shader cache, it will improve radically.

                    It's not. The HUD shows zero shaders created and zero compilations while it happens. But just now I noticed that the GTT usage drops a little bit, so I suspect something inefficient somewhere in the memory management. First thought is of course https://lists.freedesktop.org/archiv...st/001360.html but there can be no memory pressure on my 8 gigabyte rx 480...

                      As far as I know, CS:GO doesn't expose the frame time information via a parseable way to PTS (e.g. output or file) so unless there are some options I am unaware of, not possible.
