Is profiling chrome+webgpu supported?

Developer Tools Nsight Graphics

I’m using chrome and a webgpu/js webapp.

Windows 10, nvidia 546.33,
Application: NVIDIA Nsight Graphics
Version: 2023.4.1.0 (build 33678028) (public-release)

Starting chrome with: --no-sandbox --disable-gpu-watchdog --gpu-startup-dialog

I can attach (running nsight as admin), but then I get an error like “no supported API found” when clicking on start gpu trace.

Hi,

Thanks for using Nsight Graphics and share your feedback. Could you please do some check about your Chrome’s setting:

  • Your Chrome is using OpenGL as the ANGLE graphics backend
  • Your Chrome is 64bit

Thanks

Chrome Version 120.0.6099.129 (Official Build) (64-bit)
chrome://flags shows ANGLE backend: Default (which is d3d11?)

fyi, changing the angle backend to openGL makes webGPU not start.

Hi signmud,

I just realized that you are trying to debug WebGPU but not WebGL and I am sorry that I misunderstood that. Nsight just support to launch Chrome for WebGL web apps (OGL backend), I think that’s the reason for ‘no supported API found’.

Thanks
An
