Invisible npc's/ Floating nameplates

Game mode: Online/Private server
Problem: Performance
Region: US


Upon exploring there are several times where open world areas wont load in the npc’s for me. I will render in the camp or village etc, but no mobs. upon getting closer I can see the nameplates for mobs and can fight them. once killed the enemies corpse will appear. but hard to explore when I can only see a fraction of the mobs.
