WebGPU friends, I have good news! I have found a way (a hack really) to do GPU profiling while running WebGPU workloads with Chrome on Windows!
I have described the process in the following blog post, it works with at least AMD and Nvidia tools!

GPU profiling for WebGPU workloads on Windows with Chrome

Fast Forward If you’ve read the article already and/or want to jump straight to profiling, go to the TL;DR section. Context WebGPU is not a native graphics API, as in no hardware vendor provides specific drivers for their GPUs targeting this API. Instead, WebGPU runtimes like web browsers must implement backends for WebGPU using modern native APIs such as DirectX12, Vulkan or Metal. Those APIs are widely used, in particular for video games, and hardware vendors have developed great profiling tools for them.

@frguthmann Thanks for the writeup! It's a great addition to the WebGPU debugging/profiling war chest!
@brendan Thank you! Happy to contribute whenever I can :)
