You are right that they don't scatter off the media, only illuminate it. 
But you need media photons enabled to get the media lit up by the 
photons. Otherwise, there is little reason to have them. Your problems 
sound like you didn't have enough photons. It sounds like things are 
slow enough as they are, though.
What is your machine? My experiments on my 350MHz Power Mac were slow, 
but not that slow.
