  It's certainly not redundant. Not if it's optimized to only subdivide
what is being currently rendering.
  As I said earlier, this kind of optimization allows enormous subdivisions
with only a tiny extra memory requirement.

  In other words: Imagine a 100MB mesh being subdivided so that each
triangle is divided into 100 triangles, and the result can be rendered
without requiring much more than the 100MB of RAM.
