Yes a bit. Especially with media and lots of reflections.
But the real reason is for that last block that takes hours to render 
and there are cores lying idle. It annoys the bejasus out of me. :)
At least this way I can have 12 threads working on it.

That's how the modellers, I've used, work to create an animation. They 
output one scene file for every frame and use the 
Subset_Start_Frame/End, ini commands to control it.

I generally write the animation code myself. After setting the scene up 
in Bishop3D. I prefer to use frame_number rather than clock. Clock is so 
analogue ;) You know where you are with frames.
