Hello there, how to get a variable with the current number of frames per second (fps)? What is the most efficient way? I need it mainly to evaluate, recognize the situation when the fps drops so much that the game is unplayable.

You can get the fps by running `engine.getFps()`. I would recommend running this in your `engine.runRenderLoop` function and updating a HTML element you put over the top of everything.

In addition to `engine.getFps()`.  
The simplest way to know FPS is just to open the Inspector

Also, below is the button which is called “Open Realtime Perf Viewer” - a fantastic visual performance debugging tool which can help you easily identify performance issues and hiccups in your scene.
