actually, checking my figures in these articles, there is a
difference, shadow maps are about twice as quick but it surprised me at the time
that the difference wasn't greater and I think the quality difference, as long
as you don't want soft shadows, is worth the work. Having said that, though,
good hair is heavily dependany upon self shadowing and the usual single shadow
casting light methods don't work so well.
It's the ray traced soft shadows that really kill, though.
I think something like 30 times slower than hard
shadows.

I did I didn't see much difference between ray traced and depth map
shadows until I started to make the ray traced shadows soft.
Were you using hair?
