+Superluminal
+~~~~~~~~~~~~
+
+Superluminal is a commercial profiler with many features and a special focus on game development.
+It has support for profiling on Windows and some console platforms.
+
+While it does not have a free version, it has more advanced features that aren't available in the open source profilers.
+
+Here are the steps to use it:
+
+- Open Superluminal. Set the **Application** field to the Godot executable path.
+  Set the **Working Directory** to the project path.
+
+- Set the **Commandline Arguments** field based on your needs. Use ``--editor`` if you want to profile
+  the editor, for instance. You can leave it empty for profiling a running project.
+

+
+- If needed, you can adjust the **Capture Options**. The defaults are usually fine.
+  You can use this to enable child process profiling, which allows for profiling the editor
+  and running the game from it on the same session.
+
+- Click on the **Run** button to start profiling. The software will ask for elevated privileges
+  which are necessary to capture the information.
+
+- Perform the actions you need to profile on the running process.
+
+- Once done, you can close the executable, or click on the **Start Analyzing** button (which will
+  kill the executable process).

+- The results will be shown on screen. For more information on how to use this, see the
+  `Superluminal documentation <https://www.superluminal.eu/docs/documentation.html#navigating_ui>`__.
