I think theres a memory leak in valheim or something. My session last night (9PM to 1:30AM) I started with 59FPS in one place and ended with around 20FPS. Raining in both occasions and there wasn't a bunch of items on the ground nearby or anything. I quit my client and came back and it was fine. We are running the Valheim dedicated server, but since quitting and reloading the game fixed it, I'm not sure if that is related.

Has anyone else experienced the same behavior?

Windows 11
