    Wow. Just... wow.

    The progress AMD has made with their drivers makes me want an AMD-powered laptop as soon as I can get one. I'd be happy using NVIDIA but their attitude towards free drivers is just... bad.

    AMD is showing how to do things properly for Linux (I know it's not perfect with the whole DAL/DC situation, but still).

      It seems that something is heavily bottlenecking pro driver performance. Too much "good" old fglrx code still there?

      As DOTA is affected, and Vulkan is available in DOTA, running the exact same tests using the Vulkan renderer would be interesting, to see if the "hard cap" goes away.

        I wouldnt be surprised if those games will soon be able to compete with dx on windows

          If we now also could have OpenCL for all possible CIK (actually non ROCm compatible) devices including the SOCs (G series etc). Some love for Clover or hybrid pro OCL part...

            It would be nice to see a comparison. Maybe RadeonSI isn't very fast after all but AMGPU-PRO is very slow.

              amdgpu pro does not have a good openGL implementation. For gaming AMD devs for years have been focusing on the free openGL implementation in Mesa.

              amdgpu pro does have a pretty good Vulkan driver implementation though.

                70% of the performance of the proprietary driver we will get, they said.

                  Will there ever be a way for AMD to push the code in this now very performant openGL driver over to windows users as part of the crimson driver?
                  Windows users are still stuck with the slower proprietary openGL implementation. And that is not ideal for the openGL ecosystem.

                  The more uniformity the better.
                  e.g. AMD plans to share the same vulkan driver between windows and Linux by opening up amdgpu pro Vulkan
                  and Nvidia too gives similar openGL results on linux vs windows

                    There is a typo: OpenGL4.6 >> Vulkan

                      Previous tests have indicated that RadeonSI is very competitive with the NVidia driver now. Sometimes slower, sometimes even faster depending on the game, at least on these higher-end cards. I don't think Michael has done many tests with cheaper hardware. AMDGPU-Pro is definitely slow though.
