Is Heroic supposed to eat up a lot of battery?

I use Heroic on my M1 MacBook Pro (16GB RAM, 2020 model), and during the day I play approximately 1 hour of Rocket League. My battery goes from 100% to 0% in this singular hour, and my laptop is usually dead by noon. I close all background applications except for stuff that I need to keep open (today it was Firefox and Inkscape). Is this normal, and if it isn't, is there anything I can do to decrease the amount of battery that Heroic is eating up?
