I’ve never played it on anything else so it’s hard to judge.
Only got it a month ago, and have only beaten the basic game once so far, though I’ve made what feel to me giant bases.
Haven’t noticed any slow down aside from when autosave is happening. Haven’t made the kind of monstrosities I’ve seen on youtube so I don’t know where the limits are.
As someone who has wanted to play it for ages I’m having a great time with it.
Reminds me of Kerbal Space Program on PS4, the controls are very complex for a controller, but they did a great job using multiple button shift functions to map a hell of a lot to the inputs available.
I forgot to get back to you. Two days later is better than never I guess.
There’s hidden settings in Factorio if you hold down ctrl+alt while clicking the settings button in the menu. There will be a box called “The Rest” which contains more settings. One of these is for non-blocking saves on Linux/Mac at least. It allows your game to save without freezing. I have no idea if it works on the Switch or how you’d get to it without a keyboard, but I think there’s a way. I know it doesn’t work on Windows, but no one ever mentions the Switch, only that it work on Linux and Mac and not Windows.
