I have a problem where when I render in Lightwave, it will only use 25% of my processing power. It's a PC (XP) with a Core2Quad with 2 GB of RAM. The render threads are set to 4 because of the quad processor, and the segment memory limit is set to 512 so that I have one segment rendering. Also, if I take the same scene home and put it on my mac (MacPro, 2.66 Dual Dual Xenons, 6GB RAM) all 4 cores are running 100% and it gets done really quick. I'm more of a Cinema 4D/Mac guy so I'm having so trouble with this. Does anyone have any thoughts as to what might be the problem, or what I should look for?

Are you using Perspective Camera or Classic Camera? Perspective Camera must be used to have all cpus/cores keep busy..

*Or* with classic camera, threads set to 8, maybe even 16 on a quad. I always have it at 8 on my dual.
