"Maya - CPU usage 32-43% Lightwave - CPU usage 21-36% Poser 4 - CPU usage 46-89% Poser 5 (beta)- CPU usage 32-100% " Heya, the reason for this is that poser does all it's viewport rendering in software. This keeps Poser available to all the people who don't have the high-end 3D cards that are required to run Maya. (yeah I want to see hardware accelleration for Poser also. I'm sure it will come)
