title: Does the GPU process invisible things?
body: <p>I'm making a game in Unity 5, it's minecraft-like. For the world rendering I don't know if I should destroy cubes that I don't see or make them invisible. 
  My idea was to destroy them, but creating them each time they become visible would take too much processor power so I'm searching alternatives, is making them invisible a viable solution?
  I'll be loading a ton of cubes at the same time, for those unfamiliar with minecraft, <a href="http://tinyurl.com/kbvxfkd" rel="nofollow">here</a> is a screenshot so that you get the idea.
  That is just a part of what is rendered at the same time in a tipical session.</p>
