    Phoronix: Igalia's Optimizations Juicing More Graphics Performance Out Of The Raspberry Pi

    Igalia engineers José María Casanova Crespo and Maíra Canal presented at FOSDEM this past weekend in Brussels around the efforts by this open-source consulting firm to further enhance the 3D performance out of the Raspberry Pi single board computers...

    Great!
    Now let's hope that both Plasma and Gnome start this year working on Vulkan renderers.

      If I am not mistaken Gnome is already running on Vulkan when running Wayland?

        I think I heard something like that too, but it was too little to be sure.
        And I didn't understood if it's something that is part of GTK or Gnome itself.
        As I think Qt has some kind of Vulkan support too, but Plasma for sure doesn't have a Vulkan renderer so at least there everything it's clear.
        What I want is that the DEs themselves have Vulkan renderers (back-ends), similar to how some games have Vulkan renderers and everything is renderered through Vulkan drivers.

          Although they keep being vague about it, presumably they're talking about the Wayland compositors, and mutter doesn't use Vulkan for anything yet. (Not that it would make any tangible difference for the vast majority of users at this point)

          You're probably thinking of GTK4's Vulkan renderer (which works with the deprecated X backend as well BTW, it's not Wayland specific).

            Run with QSG_RHI_BACKEND=vulkan

              I think I tried it in the past I didn't notice any improvement.
              Maybe that will accelerate just a few things from Qt and not the whole Plasma itself as pretty much all the heavy stuff will still go through OpenGL ans Plasma has only an OpenGL renderer and no Vulkan renderer.

              Of course it would be better if Plasma had a proper FPS counter and not only that joke of FPS counter that they themselves warn that is no good.

                It changes the backend rendering of QML content. Plasma still uses that. Maybe the rendering isn't the slow part?
