    I vote for Windows tests. Why should it be time consuming? I mean, except for writing a Windows-compatible profile obviously. Shouldn't be as easy as plugging your external SSD with Windows and fire PTS?

    AMD: X1950XTX, HD3870, HD5870
    Intel: GMA45, HD3000 (Core i5 2500K)

      Because the writing a Windows-compatible test profile will likely take a few hours, not to mention testing for ensuring similar settings between OS, etc.

        From Feral:
        As noted in our article, we tested on both driver series and the performance difference was basically nothing. The main issue with the later driver is game crashes, not performance (from what I saw and from what Feral told me).

          Ouch

          Would be very interesting to get a Feral developer technical comment on the reason for the wide gap. Michael?
          Would be a lot less work than bench-marking 34 GPUs
          If there isn't an abstraction layer in use the problem resides in both GPU architecture and driver. Even in windows Dota 2 with vulkan requires an higher GPU usage to reach the same DX11 fps with lower minimum fps. In windows nvidia cards have higher overheads also in dx12 vs dx11. The only think they can optimize is the software part of the scheduler but I think they've already squeezed out everything.

            Why would you say there's no abstraction layer?

You could see the tide turning for a while though with Valve heavily contributing to it, and feral switching focus. Once it's open sourced and once it works on modern distros and kernels the tide will turn for AMD's official driver. For now Game Devs are not gonna support drivers which only workstation users run. Even steamOS switched to the open drivers for AMD.
              Like with opengl (radeonsi) feral's games work better with radeonsi but you always see "this driver is not supported". There is difference between "oh it works on radv" and "radv is supported by developer".
              I agree with you about reason they support radv than amd-pro-vulkan.

                I'm just saying that it's one or the other and that I don't think vulkan would outperform DX11 on nvidia cards, even without an abstraction layer.
