Open up the world, please! Part I

While it would be nicer, the game would also be much harder to run like that. The game can run on lower end PCs just fine and they can because they only have to render one zone at a time, not an entire continent.

That's not the way it works, though. as you move through a transition zone, the game unloads the zone behind you, and loads the zone in front of you. So, the game is still just loading one zone at a time.
