MacPro, Bootcamp, Windows Vista and performance

[wahit]

Hi guys!
Finally my MacPro has arrived, yet I'm having some problems here... I guess!

I've installed Windows Vista Ultimate by Bootcamp, because I need to work with Rhinoceros 3D. I also use Maxwell Render for all my rendering, and here comes the problem: I can't seem to find a big difference - or almost no difference at all - to the rendering speed of the MacPro comparing with my MacBook Pro. And they are totally different systems:

MacPro 2x 2.8Ghz QuadCore
512MB graphic card, 2GB RAM (still waiting for extra 8GB)

MacBook Pro 2.3Ghz Core2Duo
256MB graphic card, 2GB RAM


What is happening? I mean, Windows Vista here seems a lot slower comparing to Windows XP and all, but the MacPro is not a MacBook Pro. It's supposed to be much faster!

Do you think I'll get better results if I go back to Windows XP (32bit) and render all all stuff there? Or maybe trying Maxwell Render 32bit version instead of the 64bit I'm using?

Or is there any way I could install and get all the drivers working for Windows XP 64bit?! Because Apple doesn't suply support for this version of Windows XP...

Thanks!

What's your memory usage? If you are using all 2GB then that's probably what's holding you back.

How can I see that on Vista?

Is RAM usage a major influence on rendering speeds?

We could use a bit more information here.
You can get some performance data from
the Task Manager and Resource Monitor.

For example: are you hammering all 8 cores?
