I bought a watt meter to test how much power my computer is using, when UE4 is in idle, it still uses approximately 170watts on my computer.
Now that is of course, relative to my computer and GPU, I am running a GTX 570, a fairly power hungry card, it is costing me approximately an additional 7c an hour to run unreal engine on my computer. This might seem like it doesn’t mean much, but for me it means I need to be consious, not to have UE4 running in the background when I am not using, I would probably use my computer for 70hours a week, that’s about $5 a week if I keep UE4 running the whole time and an extra $20 a month to my power-bill, thus UE4 is as expensive to run, as it is to subscribe to.
My electricity is not super expensive here, it is like 0.25c a kilowatt hour. My math is a little bit wonky here, but this is something epic can test itself, there is no need to take my word for it and an issue I’d like to bring to the community and if there is a simple fix, I’d like someone to implement that.
Here is a video I made about this: - YouTube .
