I'm in a dire situation. I bought a new G4 Dual 867 Mac that has a lot of spunk. I thought it best to graduate to it from my old G4 450. What I'm having trouble with is that the scene files that I open on the 450 open relatively quickly (about 4 minutes) whereas on the 867 the same scene will take anywhere from 10-15 minutes.

I've also hit a bit of a ••••• when the 867 calculates shadow maps for the scene. It takes forever. whereas the 450 calculates the shadow maps in about 5 minutes or so.

Any and all help appreciated ASAP. You can reply directly to my email box, arlen@fabmedia.com

thanks in advance.
Arlen

PS.
I guess i should add that the G4 450 is not a dual processor machine and that I'll crash during a render after the computation of the shadow maps... arrrrgh.

if your scen is not too big, send it to me:
nostrom@noos.fr
I can try and load it on my mac (1 dual 500 and 1 dual 800 with os X.2). So we'll see if the problem comes from your machine or from your scene.

Okay, I won't be able to do it today, but I will make it available for download later today or tomorrow. I need to get everything together then I'll send you and email. I might be able to have it ready late tonight. Do you have Saskwatch?

I noticed that with using the CPU monitor that the processors are only functioning at 1/3 to 1/2 of the total processing capability. As a test, I started another application to see if the processors increased in computing potential, and I was right. They maxed out at 100%. Any ideas?

to increase the processors work, did you try to put 2,4 or 8 threads in the render options panel ?

Yes. I've tried everything. I've been getting a little frustrated with this whole thing. I'm not sure what to think anymore. The processor is only clocking at 1/3 to 1/2 speed on both processors.

hmmmm...
