What features?

  Personally, the ones I'm most looking forward to: * Subgroup operations * Push constants (available in wgpu, but not WebGPU the spec/web impl) * u64 + atomic image ops * Mesh shaders * Raytracing * Binding arrays / descriptor indexing + device buffer addresses

    Similar. I've done experiments with subgroups suggesting approximately a 2.5x speedup for sorting (using the WLMS technique of Onesweep). Binding arrays will be very helpful for rendering images in the compute shader. A caveat is that descriptor indexing is not supported on mid-old phones like Pixel 4, but it is on Pixel 6. I somewhat doubt device buffer address will be supported, as I think the security aspect is complicated (it resembles a raw pointer), but it's possible they'll figure out how to do it.
