It will start by asking what kind of plan you want it to be, pick "High Performance." Then there are some settings about turning off the display (do whatever you want) and putting the computer to sleep (which personally I'm not a fan of, at least for desktop computers).

After you create the plan, you can click "Change plan settings" next to it, and then "Change advanced power settings," but I'm not sure any of them need to be tweaked. In mine on this computer (not my rendering computer), I have "Intel Graphics Settings" which can be set to "Maximum Performance". And Processor Power Management, you'd certainly want Maximum Processor State to be 100% and System Cooling Policy to be Active. You could raise the Minimum Processor State too, not sure how important that is for sustained tasks though.
