* Enforce a frame rate limit. This forces how often the Game step will run. By default it is zero,

* is the optimum rate for fast-action games. However, if you are building a non-game like a graphics
* generator, or low-intensity game, you can lower the step rate via this value (and its related config

* Use it purely to _restrict_ updates in low-intensity situations.
