Burst is a CPU platform bult on C#, it doesn’t directly relate to WebGPU (other than they are both features of Unity). I don’t think Burst can be implemented without C# multithreading support, which Unity currently can’t do because of WASM limitations with multithreaded garbage collection. I do know there is active research going on for trying to figure it out. I do appreciate how important multithreaded C#, and Burst, will be.
