Cullium

Cullium is a lightweight client-side performance mod that stops Minecraft from wasting time rendering things you can't see anyway.

What it does

• Invisible entities — Any entity with the invisibility effect, or marked invisible via commands, is completely skipped. No shadow, no name tag, nothing processed at all.
• Orphaned block entities — Chests, signs, banners and other block entities that have been removed or are sitting in air are skipped entirely.

Why it helps

Vanilla Minecraft still processes invisible entities through a large chunk of the render pipeline even though nothing shows up on screen. In servers or worlds with lots of invisible entities this adds up fast. Cullium cuts that work out completely.

Compatibility

• Minecraft 1.21.1
• Fabric Loader
• Requires Fabric API

Notes

This is a client-side only mod — it does not need to be installed on the server. Should be compatible with most other mods.
