You need to add

-console

to your command line options for Valheim first, if your don't have that.

This should fix up some of the FPS issues.

Woah. I did not saw this fix. Thanks! Will try again!

You're still not really intended to build a "castle", there aren't even enough items in the game to decorate a huge base. If you build ridiculous things it's still gonna lag.
