@monkeycloud: I just tested on my 6-core Windows using Tmonitor from CPUID as well (don't know if there is something similar for mac).. Got similar numbers from taskmanager but:
those processes are a mix of singe and multi thread steps, so you'll get average numbers for the mix. The launcher for the multi-threading is always single threaded by itself (like: there is always only one manager process in queue/network rendering).
the multi thread parts are definitely present, but very short in individual length (say 0.2 sec each). I could see that in Tmonitor, which reports at 20 views per second. Each CPU thread gave about 1 burst per sec.
the taskmanager reporting steps are larger (high speed = 0.5 sec, normal = 1 sec), so you'll get a single/multi-mix average over the period. Some math: 100% load at 20% of the time + 8% load (I've got 12 CPU threads) x 80% of the time = 26% load average.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
