UPDATE: Just found out that with complex scenes (hdri.c4d out of the 9.52 lib) the cpu-peaks reaches nearly 100% while rendering one complex frame. When it beginns with the next frame all cpus drop down to 0% for a few secs and then boosts back to 100%.
So with less complex scenes the periods of rendering from frame to frame are much shorter, which means more cpu peaks and less full usage of the cpus.
Also I found it strange that the Ram usage never extends 1 Gb with c4D. Is that normal for even complex scenes? I mean I have 16 GB ram on my system and the feeling I never could use it with c4D, with After Effects I need all the time at least 10 GB to work smoothly.
