    Just curious, did you go through the benchmarks in detail or just read comments ? The AMDVLK driver is faster than the latest closed source version (17.50) in as many graphs as it is slower.

      With respect, the key question is how we best compete with NVidia given the realities of available R&D budget. Do we:

      - pull people off other parts of the open source driver work so we can have them add support for new HW generations to RADV instead...
      - wait until a few months after each new HW launch for Dave and others to have time to add support themselves...

      ... or do we leverage PAL work being done for other OSes & APIs in AMDVLK and maybe even in radeonsi, and use relatively more of our Linux budget for things that really need to be Linux-specific ?

        As far as I know, it would be incorrect to claim that Vulkan is created by AMD. Acording to the wiki, Khronos Group develops it, and it consist from all sorts of companies including AMD, nvidia and Intel. AMD did created Mantle, and latter (potentially) incorporated parts in Microsoft DirectX 12.

          We should probably see Vega cards having bigger gains over the rx580 in all honesty, ins't Vega almost twice the compute performance? so hopefully more driver optimisation makes that realisation happen!

            Right. AMD contributed Mantle to Khronos as a starting point for what became Vulkan, although Vulkan did end up pretty close to Mantle in a number of respects.

              That's kind of confusing, since AFAIK "Radeon Software" is what we call the entire stack. Maybe you mean "Radeon Settings" ?

                Yeah, the problem right now is Linux games are hitting the CPU-bound point relatively sooner than we see on Windows - may be related to the prevalence of porting frameworks but not sure yet - and once you hit that point you see much less scaling with GPU performance.

                  Of course. We focus on Windows. The new driver (17.50) was renamed as "Radeon Software for Linux", which introduces confusion. This driver can not be so named until it completely corresponds to the "Radeon Software for Windows" package.

                  And Yes, I'm asking about the panel and its guts

                    Let's talk about Radeon Settings instead of Radeon Software then - that's what we call the control panel AFAIK.

                      OK, let's go))
                      Once the name of the driver package has become more like a package for Windows, so we are getting closer and closer to erase more of the boundaries between operating systems?
                      What stands in the way of porting the "Radeon Settings" on Linux?
                      Surely for the sake of marketing will have to wait for 11 December 2018, when there will be some "Alizar Edition", which together with the new features for the driver and will bring the full panel for Linux?
