    Phoronix: AMDVLK 2019.Q2.3 Has Improvements For Some Games, LLPC Optimization

    It's been a few weeks since AMD developers last updated the public source trees making up their official open-source "AMDVLK" Vulkan driver but out this morning is v2019.Q2.3 as their newest update...

    (I'll have out a new RADV vs. AMDVLK comparison in the coming days)
    Neat! TW: WH2, Mad Max, RotT, DXVK plz! :-)

      Michael Could you set dxgi.maxFrameLatency = 1 in dxvk.conf? There are cases where amdvlk has a higher input latency, thus I think using this setting would be fair. I also saw amdvlk losing more fps with it than radv (hardly any loss with the latter).

        People, automated benchmarks and benchmark modes should be in the past. Nvidia's non lossless graphics give fake results. Better search Youtube for real gameplay benchmarks and if you can make one your self: https://www.youtube.com/watch?v=TbvQVgesZ_s

          Source links and a pre-built Ubuntu x86_64 Vulkan driver package are available via GitHub.
          For users of Ubuntu and derivatives rather than this method I wonder whether AMD would consider setting up a PPA.
          It would be a very good move to increase the userbase of this driver and keep it updated, which is much needed at this point. Right now it's just simpler for everyone to stick with RadV.

            humbug There's an apt repository at http://repo.radeon.com/amdvlk/apt/debian/

            Code:
            wget -qO - http://repo.radeon.com/amdvlk/apt/debian/amdvlk.gpg.key | sudo apt-key add -  
            echo 'deb [arch=amd64] http://repo.radeon.com/amdvlk/apt/debian/ bionic main' | sudo tee /etc/apt/sources.list.d/amdvlk.list
            sudo apt update
            sudo apt install amdvlk

                Hm, it's now faster in Heroes of the Storm with prerenderlimit 1 (radv 170fps, amdvlk 176fps, Windows DX11 188fps). In some scenes like the closing screen (has some kind of particle effect which causes extreme power consumption) the difference also seems bigger.

                  Built amdvlk-git+proton based on 4.8 staging+DXVK master & AGS 5.0 and it gets within 1.5 FPS of RADV on the Miama benchmark of Hitman 2. AMDVLK gets 35.75 and RADV gets 37.1 after running each 4 times to build up shader cache.

                  Here's what's interesting -- AMDVLK didn't lag or skip anywhere near as much during the intensive pull-out scenes. While I'd need to actually play to tell y'all more, AMDVLK appeared smoother even though the FPS was lower. I also noticed that Wine detects my GPU as "Radeon RX 580 series" when using AMDVLK or AMDVLK-Pro and with RADV it's "AMD RADV Polaris10 (LLV...", it cuts of after the LLV. If you're RX card keeps coming up as the wrong GPU, try running it with AMDVLK and it might report properly.

                  All compiled using Ofast, march=native, and mtune=native & I tweaked proton-tkg.sh to include native and fast for the winegcc/g++ parts.

                  Update: Played a little bit last night and, in game, I didn't really notice any difference between AMDVLK 2019.Q2.3 or RADV from Mesa 19.0.3. Both have the same odd graphical bug if you look at a light source through multiple translucent surfaces. A good test and way to trigger that bug is in the free level Hawke's Bay -- on the 2nd floor next to the bedroom, turn and look towards the light in the pool room through the balcony and the pool room glass wall. The current/latest Ubuntu AMDVLK-Pro is unusable with Hitman 2...it works and renders stuff, but it's very choppy.

                    skeevy420 You may have fed DXVK's pipeline cache in the first run with radv which would also benefit amdvlk in subsequent runs.
