Is that difference how people would actually understand the word? I&#x27;ve never (knowingly) heard it used like that. Certainly terms like &quot;CPU utilization&quot; and &quot;network utilization&quot; are frequently used to denote a simple use-divided-by-capacity ratio.<p>For your game example, I don&#x27;t see what isn&#x27;t encompassed by &quot;speed&quot; (how many FPS you get out) or &quot;efficiency&quot; (how much CPU&#x2F;GPU you use to do it).
