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!
