Factorio Forums

Hello,
I have a big inefficient spaghetti factory. It's a mess but I love it. My UPS is pretty low, but my CPU usage is not very high. Factorio is only using 21% and there's plenty of RAM left over too. Is there anything I can do to help factorio use more of my CPU? There's plenty available.

This is on a Ryzen 9 5900H

CPU usage is a percentage across all cores, but Factorio is primarily limited by single core performance and RAM latency. It is multi-threaded but there are limits to how much can be done in threads so single core performance is more important. There's not much you can do about it, there are just too many calculations that need to be done.
