Backface culling

Is backface culling a hard algorithm and does it really speed up performace. If it isn't a hard algorithm for a newbie and does really help could someone give me and idea of how to accomplish it.

It's not hard at all, just use glEnable(GL_CULL_FACE); and OpenGL will do the rest for you.

THATS IT. that simple little line. cool. i put that in my draw scene loop i guess?

oops i mean in my create window right?
