I tested with the flags and adding the --enable-Vulkan switch, but to no avail. But I have a somewhat non-standard setup both software and hardware, so I'm not terribly surprised. (Kubuntu 22.04 on an MSI laptop with an nvidia 3060, using proprietary non-free/blob driver 535.)
I will be playing with webGPU in the coming weeks on a number of platforms, seems like a no-brainer for the current state of AI stuff.
It really is too bad WebGPU isn't supported on Linux, I mean, that's a no-brainer right there.
