It's mostly used for debugging & finding out information about your game when it's running. For example you can display the log on the screen, or you could change the scene, character, change a condition or set a value. Display information about a specific animation or a list of active animations along with various information.

Besides the developer console there is another tool (overlay) for displaying a live feedback of used ram, vram, cache, cpu etc by pressing the HOME (POS1) key on your keyboard.
