Affordance: the quality or property of an object that defines its possible uses or makes clear how it can or should be used
Feedback: indication that an action was initiated, completed, or is newly possible.
But how can I apply this to computers and my applications?
A display's refresh rate will dictate how often your "picture book" frames need to be. You'll see this measured in hertz. 1 Hz = 1 cycle per second.
If your application can not render in time it will drop frames which manifests itself as
jitter or unsmooth animations. It can really negatively impact UX, and even cause nausea for
certain devices and form factors.
DO NOT DROP FRAMES!
