I am trying very high lag peaks near spawners with innovation eggs!
When I look far away to the mob spawners region my fps drops from 110 to less than 30!!!

I have almost all possible mods that help in optimizing the game, I already took sodium out completely and put it back!
Result: When I removed the monster eggs from the spawners my fps returned immediately!

I cannot find the mod you have mentioned which makes it hard for me to search for a solution. It sounds like a rendering issue with the innovation (mobs?) inside the spawner.

I was talking about the Enhanced Mobs Spawners! I was with a modpack in version 1.16.5, and I was having extreme lag when looking at a spawner mob with some mob placed by me (Player)!

After a while/update, it must have been fixed since it hadn't responded before.
