Right forgot about that one! that it's included now. trying it. It  
created 4 process(+ the afx main process) and for each process, 38  
threads, it's own processor with 400mb ram, and each processor is  
running at around 93-113%. I don't know how accurate the aftereffect  
est. remain is but it looks like it might cut the render from 2 hours  
to an hour. Good one on the tip Martin thanks.

I used to use this plugin pre-CS3, but then started to have some  
issues with it as far as crashing.

all sorts of background rendering, even stuff that let you render and  
work at the same time, I should check it out again

thanks again Martin
