I'm making some escape room map with immersive portals mod, everything is fine when im on creative mode, but when i switch to spectator/adventure/survival, minecraft goes 1fps, I don't really know why.

Minecraft version: 1.16.5
Mod version: 0.101

oh and map has like 100+ portals, but even with 1 portal its laggy, i have good specs

Are you using other mods?

Only pehkui

Close because outdated.
