In this instance, the only way to access the Profiler is to launch it through the Unity Editor and connect it to a running instance of our application. We will use the same Profiler windows irrespective of whether we execute our game in Playmode within the Editor, running a standalone application on the local or remote device, or wish to profile the Editor itself.
