As long as you don't set the priority to high, you should set WT to the
actual number of logical cores.
For 6 cores with 12 logical cores, you should use +wt12.
Also, by default, POV-Ray version 1.7 and later is be set to use all the
logical cores present. At least, that's the case on my computer.
Yes, the «duty cycle» is present since version 1.6. It can be set from
10% to 100% in 10% increments, and yes, it was implemented for use on
What can make your CPU time go lower could be thermal throttling. This
can happen if there is to much dust in the heat sink of the CPU. It
should be cleaned at least once a year, more if you are in a dusty
Some other possible causes would be another CPU hungry process running,
or memory use getting to high and swapping start happening.
