Alright everyone, this one has really been driving me crazy. I have a Mac Pro 8 core 3GHz 16GB ram with a Radeon X1900 graphics card (should be beastly at 3D rendering, right?). I use cheetah3d for my renders. At this moment, the mac pro is rendering slower than my blackbook 2.0, in some cases by significant amounts (7 secs on blackbook vs. 13 secs on the Mac Pro). I was astonished by this, so I took a look at Activity Monitor to see what was going on. Well, according to Activity Monitor, the mac pro was only using 10% of it's total processing power while rendering. My blackbook uses every bit of power it can get. All I can say is WTF?? At this moment, the Mac Pro is useless to me. Does anyone have any idea what is going on? Thank You!
