It says this under Firefly Rendering in the Poser 12 manual:

Multi-threaded Rendering: The Multi-threaded Rendering feature takes advantage of the increased processing power of the multi-processor or multi-core computer systems that are now available. Using this feature, you can configure FireFly to render any number of separate threads simultaneously, which results in reduced render times for most renders. The number of threads can be specified in the General Preferences dialog (see Render Preferences for more information).

But when I go to General Preferences/Render/Number of threads, it only goes to 32.
