Staying on topic, as Trakehner mentioned, Valheim is in Early Access, as the game's main page already says so. The game is created by an Indie studio by two main developers. So this 'unoptimized nonsense' you're speaking of is due to these two reasons. It's just how it works. Not every development house uses the same framework to create their apps. So while some developers may focus on optimization early on, others won't.

Right now, the game is at Milestone 2, which they are working on the Mistlands biome content. The current version is v0.204.4, which is a long way from v1.0. Let's see how the game performs at around v0.8.
