Can somebody help with this problem? I'm using the new athlon dual MPs on Windows XP, my workstation is fully equiped(not trying to brag, but just to let u know of my problem is not hopefully due to hardware)! Anyways, when rendering in a 3D program(supports multiple CPUs), does anyone know why when I checked in task manager I am only using 50% of my CPUs? As the same render in my friends'computer, uses 100% CPU using single P4 1.7Ghz and Win2000???
