Hi
If you are using Blender on Windows with Intel CPUs on a render farm or if you tend to send Blender into the background while rendering (e.g. reading emails), you might want to take a look at this free plugin:
“Do you use the “new” Intel CPUs (12xxx, 13xxx and following) on Windows?
If you do: If you render with Blender and might switch the application while you wait for the frame to finish or if you use Blender on your render farm, then it uses a slow fraction of your CPUs total power!”
