Stuff I don't need to See

I am searching for a way of wording this topic.
I have an age Enobmort where at any one time you have a limited viewpoint where you can only see the section of corridor you are in. In fact once I work out a method of inputting a value there will be doors that limit you to sections not unlike Kadish. One puzzle is reliant on you closing a door so that it opens a door elswhere in the age so that someone else can push a button that opens your next door. (I know too much detail)
I believe theres a way of getting Uru to only worry about the rendering of surface detail in your near vicinity therefore freeing up processing power and reducing lag.
I can't find anywhere where this is explained/tutorialised (I apologize for the made up word tutorialised).
Can anyone shed some light on this subject?
