What part of WebGPU isn't meeting graphics performance? AFAICT it's only people who continue to treat it like WebGL. It's like C++ programmers complaining Rust is slow and then Rust programmers say "stop using it like C++". If you want perf in a low-level API liek WebGPU you have to work with it using patterns that fit. If you stick to your WebGL patterns then yea, your app will suck.
