Important: Chrome may use SwiftShader (software GPU) instead of your real GPU. This makes inference 100-1000x slower! Launch Chrome with special flags to enable hardware WebGPU.

Verify GPU Status

After launching, check the backend indicator above. It should show WEBGPU and the log should show your actual GPU (e.g., "nvidia blackwell", "AMD", etc.) - NOT "google swiftshader".

You can also visit chrome://gpu to verify WebGPU is using hardware acceleration.
