So, I recently opened a Realms server with a couple friends. Yesterday when I logged in, the FPS dropped significantly and I can't figure why.
The only farm I built is a villager breeder, and it only spawned three of them so I don't think that's the reason.
Also everything seems fine in the nether, FPS only drops in the overworld. I checked my entities I have about 190 loaded around my base for 100 in the nether, so it doesn't seem to be the issue either.
What else can I try to find the cause of that lag ? It's barely playable right now i'd really like to fix it
