I'm sitting here for 8 minutes watching a segment render. I open up my activity monitor and only about 25% of my cpu usage graph is taken up. My disk activity is only 3-4 mb/sec so it's not disk limits. Does this mean all the processors/cores on my mac pro are just sitting here being wasted? SO frustrating, because I bought this machine to get things done FASTER and it looks like it's just going to waste.
