    nvidia plz, stop being so far behind amd and gib open source official drivers.

    Vulkan drivers can fall back to a CPU path for things that are either not supported in the hardware it runs on or if that function is not yet implemented in the driver.
    That's for example how the Vulkan Driver on the Raspi gets good compliance, many things are done on the CPU.
    If anything that mattered wasn't implemented in hardware, nvidia's drivers would suck too.

    Maybe, it does not make sense to you. But the question given perfectly makes the sense to me. Anyway, I agree with you that you probably do not want to emulate too many things on CPU for performance reasons and for NVK and Nvidia hardware it is probably true underscored two times.

    I wonder what the status of hardware video acceleration on nvidia gpus with nouveau is.

    Not really, you can't fallback to software for that much, definitely not for anything that has to work in real applications, I doubt even the rpi does things as badly as you think. You also don't fallback to software for things the hardware can do, that would be a lot of extra work and mostly pointless.

    I wonder how much of that is actually implemented in hardware, and how much of that is compliance fallback.

    Performance tests are needed.

    hmm.. does Debian have anything to do with this driver?
    FreeDesktop.org / Mesa is a member of Software in the Public Interest (SPI), just as Debian and various other open-source projects are.
