Hi,
I have a late 2012 27" iMac 3.4GHz Quad core i7 with plenty of RAM and I am getting very long render times in lightroom (30 minutes). It seems that my CPU is anywhere from 40-70% idle during the process. Also my graphics card GTX 680MX seems completely idle during the process. Is LTR render in Lightroom just not able to use all of my system resources? Or am i doing something wrong?
   

I've also included a screenshot of my CPU activity during my export to video in LTR compared with the render in lightroom (left on the graph)
   

It's Lightroom not using multi-processing ressurces when exporting - unfortunately. You might export different sequences at one time, this will raise processor load.
