    Phoronix: The Vulkan Overlay Can Display Some Extra Information With Mesa 19.1

    One of the early features merged back in February for Mesa 19.1 was the new Vulkan Overlay layer to expose various performance metrics akin to the Gallium3D "HUD" also living within Mesa. Ahead of the Mesa 19.1 feature freeze, some more capabilities are now added to this Vulkan overlay/HUD...

    CPU and GPU load would be very useful.

      To see all current config options, use:

      Code:
      VK_INSTANCE_LAYERS=VK_LAYER_MESA_overlay VK_LAYER_MESA_OVERLAY_CONFIG=help vkcube
      See: https://gitlab.freedesktop.org/mesa/...y-layer/README

        Michael will this give you the ability to make lots of additional graphs when benching Windows games on DXVK and native Vulkan titles?

          Not much. You have framerate and frametime which DXVK_HUD also provides. Other stats I find most useful are GPU and CPU utilization which neither of them have. The rest are already more esoteric stats.

            A time series graph of CPU/GPU usage and FPS would be awesome - throw in some Disk latecy to detect spikes there that might affect framerate and you have a deep dive in a graph

              Is this available by default in Mesa 19.1 or does it need to activated through build options?

                This isn't building for me with Clang or GCC
