it improves the performance and takes stress of your gpu and increases fps

portaling splits your map into "cells" which the game will just render stuff inside the cells that are in the players fov.
and basically to portal a map you must do those cells using structutral brushes which wont let the player look to the other side(you can caulk them and see that what is behind wont be rendered) and if you have somwthing like a window you add the blue portal texture to an structural bush. blackjohnys tut xplains in more deep how to use them.
