Superluminal is a sampling profiler, it halts the CPU at 8-40khz (depending on platform) and reads the state of the stack. So more data is better data, and looking at individual traces might not produce extremely accurate results like a traditional instrumentation profiler. So when you're looking at timings note that while you can use it like Unity's profiler, you'll likely get better results by selecting a large range of the capture that you think contains the issue.


  1. Install Superluminal and note where you installed it.
  2. In the Unity Hub use the dropdown next to the project to Add Command line arguments. Add -monoProfiler superluminal
  3. Copy the mono profiling dll from Superluminal to Unity:
    1. In the Hub, find your 2019.4.40 install and show in explorer.
    2. Find the Superluminal install and open the Unity > x64 directory.
    3. Copy the mono-profiler-superluminal.dll into the Unity install directory, next to the exe.
  4. Reopen the Unity project.
  5. In Superluminal add http://symbolserver.unity3d.com/ to the symbol file locations.
  6. When you use the Attach menu to attach to Unity.exe, it will start profiling immediately, so only do it when you're ready to profile!
