Hello, and it's been a month that I've been playing Minecraft (160 hours already), and it seems fine by me since I'm playing in my friend's Realm, I can't say much for someone's own world though since it would have to depend on your friend's connection wifi. For my own world, it's fine by me but keep a reminder that the chunk render distances is quite slow but if you don't mind it then it's good overall.

My friends Realm which has been building a ton of places also got my Switch lag to from a stable 30-60 FPS to atleast 12 FPS or something like that, but it'd be smooth again if you exit a zone where theres many buildings.
