    Last time Michael tried this on a high-core-count machine, I think he found that performance maxed out at like 16 cores.

    airlied 's blog entry doesn't specify what CPU this latest test used. I didn't check to see if his earlier entries mentioned what HW platform he's using.

    Cool, up to 10 fpm of pure performane.

    If we can get graphene CPUs and they you could go 1,000x times faster, (like they say) that's 166fps.

    It's interesting to hear how this is progressing.

    much of the overhead is due to BPTC texture loading that Airlie hasn't yet optimized for Lavapipe
    I wonder if there's a good, generic way to profile JIT code. operf certainly hasn't done me much good, but then I haven't really looked into it, either.

    those dreaming of real and legitimate gaming with Lavapipe on the CPU with modern CPUs are still living on a fantasy island.
    An order of magnitude less than real GPU performance probably isn't unreasonable to hope for, though it probably depends somewhat on how much the app leans on HW features vs. generic shader code.

    Phoronix: David Airlie Tries DOOM On CPU-Based Lavapipe Vulkan

    Red Hat graphics driver developer David Airlie has tried running the DOOM (2016) game on the CPU-based Lavapipe Vulkan driver... It works, but isn't fast and currently requires some hacks...
