The Qualcomm Snapdragon Profiler allows developers to analyze performance on Android devices with Snapdragon processors over USB, including CPU, GPU, memory, power, and thermal performance. The Sanpdragon profiler is available for Windows, macOS, and Linux.
Samsung Snapdragon phones running VrDriver 1.5.3 and later auto-detect when Snapdragon Profiler is running, and configure themselves for best capture.
- Download and install the Snapdragon Profiler from Qualcomm.
- Attach an Oculus Quest.
- Run Snapdragon Profiler. It is important to do this before starting the VR app you want to use.
- Select Connect to a Device. If you do this right after starting, you may need to wait a few seconds for the phone icon to turn green (driver files are being transferred).
- Click connect.
- Run the VR app that you want to profile. Note that you will see poor performance because of optimizations related to the performance testing - it will not affect your session.
- Select either trace or snapshot capture modes.
- In the “Data Sources” panel, select the app name. Note that only applications with the OpenGL requirement set in the manifest will show up. If the application has the required manifest setting but does not appear, try rebooting the phone and restarting the Snapdragon Profiler.
- For traces, enable OpenGL ES -> Rendering stages for the most useful information, then click start capture, wait a second or two, and click stop capture.
- For snapshots, you can capture a frame of commands without any extra options checked. The capture process can take tens of seconds if there is a lot of texture data to transfer
- We recommend shutting down and restarting the Snapdragon Profiler between sets of tests.
- Quit Snapdragon Profiler before unplugging your device so it can clean up. Don’t forget this step!
