OK. I REBUILT AE pref. file, I am not using Open GL, I usually don’t. I did a test with MUTTIPROCESSING turned OFF ( 8GB allocated for other Apps) render time = 4min 5secs. ( I also checked the activity Monitor while rendering, It was up and all the way down …..sporatik, but all were never up at the same time. Then I did a test with MULTIPROCESSING turned ON, here were my settings (4GB ram for other apps, 2.09 GB min. allocation per CPU, 6 actual CPU’s that will be used, 2 CPU’s to leave for other apps, render time = 3min. 1sec. (activity monitor was up and down just like the other render, except for the end they were all the way to the top for the last portion of the render. Still does not come close to the render time of the slower MAC.
