WebGPU will always have the issue to lang behind native capabilities.

It is good enough if aiming to PS3 like games, though.

It's heavily sandboxed, and there are other overheads to get around.

And has 2015 state of the art hardware as inspiration, in 10 years time we might finally get mesh shaders and raytracing, looking at how long it took to get OpenGL ES 3.1 compute shaders available.
