I am trying to make sense of this:
While Rendering this scene in lightwave I see:
How can I be using 183% of my processor?
I have dual processors, is that what I am seeing?
The viewer went as high as 190% for all 47 minutes.
What am I actually seeing with > 100% ?

You've got a dual processor machine, don't you? I wish Bryce had that kind of multithreading... my poor second processor is just going to waste.

That's percentage of one CPU, so if it's greater than 100%, then it's using more than one full-time-equivalent-CPU.

I tried the demo version Bryce some time ago. I didn't like it. With this thing taking 45 minutes plus, I wonder how much the dual processor helped me?

As others have explained, you can have one processor use more than 100% CPU if it is multi-threaded and has threads running on both.

Makes sense, but I've seen the same thing a number of times on my single processor machine. I figured it was just a bug in "ps" so I didn't bother to ask about it.

Did you adjust 'multithreading' in the rendering options of lightwave? that will decrease rendering times- its a bit of a black art though. If you try 2,4,8,or 16 on a scene it will make a difference- but as to which one to use for a particular scene, its hard to work out... or try decreasing the polygon count- its amazing how little you need to get perfect visual results. Or am I preaching to the choir?

I wish. I am totally green to LightWave. Just trying to learn in.
Right now I have it set to 4.
I guess though, the only way to know if one way is faster then the other would be to render the same scene several times?
