In PIX, Select Target Process => Launch Win32 and set the following 2 entries according to where Canary / Chrome is installed:
- Path to executable: "C:\Users\alexis\AppData\Local\Google\Chrome SxS\Application\chrome.exe"
- Working directory: "C:\Users\alexis\AppData\Local\Google\Chrome SxS\Application"
- Command line arguments: --disable-gpu-sandbox --disable-direct-composition
- You can add those arguments if you want to be able to see the disassembled shader code: --enable-dawn-features=emit_hlsl_debug_symbols,disable_symbol_renaming
- Launch Suspended unchecked, Launch for GPU capture and Force D3D11On12 checked
Then click on "Launch".
Important: you should close all your Canary / Chrome windows/processes before clicking on the "Launch" button!
To Capture a frame (GPU Capture frame):
- Choose Present-to-Present
- Click on the Capture icon
- You probably need to set Capture frame count to 2 (I had to), otherwise the capture won't contain your commands, only those of Canary / Chrome
- If you do other captures you can get an "An error occurred during capture" popup: just close it, the capture does work (at least it works for me).
If you want the debug markers to work inside PIX, you need to perform those steps: https://dawn.googlesource.com/dawn/+/refs/heads/main/docs/debug_markers.md
Notes:
- I could not locate the libdawn_native.dll file: I have simply copied the WinPixEventRuntime.dll file into "C:\Users\alexis\AppData\Local\Google\Chrome SxS\Application<version>" and it did work
- If you update Canary / Chrome, this file will be removed, you will have to copy it again
I tested many parameters (including dump_shaders), but it still doesn't work.
Thank you again for your help.
