I recently discovered that Blender (the open source 3D
modeler, renderer and steep learning curve kitchen sink) only uses one CPU by default. It is
possible to change the number of threads that Blender should use in the render settings. I expected
the optimal number of threads would be the same as the number of CPUs. My good old Mac G5 has two
CPUs, but eight threads (the maximum) actually renders a little faster than two. The big difference
is seen between one and two threads though. Your mileage may vary of course, but if you're a
Blender user who hasn't seen this setting before, try tweaking it!
Set maximum threads in Blender!
