Playing minecraft on switch vs my pixel 6 is night and day. I can't imagine performance is anywhere near what it needs to be for an end game base? But I'd be curious to see what they've come up with here.
One of the first questions you might ask is how does the game perform. We worked on many optimizations to make sure the game performs as well as possible. You should expect 30-60 FPS (both in TV mode and handheld mode). As for UPS, the average player should be able to go through all of the content and launch a rocket, while staying at 60 UPS. But don't expect to be able to build mega-bases without UPS starting to drop, sometimes significantly.
Edit: I guess the client also has to run the simulation, never mind. It seems like overall, Factorio is well under-optimized though. For a game that has been out forever, it still has a huge ceiling.
The Factorio devs regularly put out blog posts on the optimisations they have done, like [1][2][3] (and many others), and they have done so for a long time. This gives me the opposite impression.

I know it’s a well optimized piece of software, but when you get into something like the space mod with multiple worlds, where chunks you might not deal with for a long time still tax you, you can see how there’s conceivably a lot that could be done.
So, yeah, wrong to say “under optimized”.
I’m also aware that they haven’t been optimizing for a massive multi-world server with tons of clients. I definitely don’t mean it as a dig or that they aren’t top class.
