Great to hear that you could successfully create the trace file!
To analyze the trace file, you'll need a tool called Windows Performance Analyzer (WPA), which is part of the Windows Performance Toolkit. It can open your `.etl` file and provide you with a detailed look at what was happening in your system at the time.
Here's a brief step to do this:
1. Download and install the latest version of Windows Assessment and Deployment Kit (ADK) for Windows 10. You can download it from Microsoft's official site.
2. During installation, you can uncheck all other options and just check "Windows Performance Toolkit".
3. Once it's installed, you can find WPA in your Start menu.
To analyze a GPU problem specifically:
1. Start WPR.exe.
2. From the "Select additional profiles for performance recording" section, check the box next to GPU Usage and then click on "Start".
3. Once done, stop the recording using WPR.exe, and this will create a trace file.
4. Open this file with WPA.exe.
Once you open the trace file, WPA presents a hierarchical view of the data. In your case, look at the `GPU Usage` graph, which presents data about the activity of the GPU during the collection time.
Reading these graphs and data takes some understanding of system operations, but in a nutshell, you're looking for persistent high usage and/or large spikes in activity which may indicate the source of problems.
Remember, interpreting WPA results can be complex, as the Windows operating system is a complicated system with many components. This might be a start, but you may need further assistance depending on the complexity of the issue you're trying to resolve. Don't hesitate to post on our forum if you need more help with
