Displacement popping problem 2004-06-02 - By kim aldis

My experience has definitely been that length/distance/angle isn't that
reliable. In fact, fine came to us in 3.5 as an improvement on that method.
Fine along with view dependancy will subdee to sub-pixel level where you
won't see any of the crap that goes with the old adaptive method. My advice;
always use fine/view dependance.
