by hydrogen001 · on CurseForge

A high-performance, lightweight rendering optimizer that boosts FPS by intelligently culling distant and invisible particles.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.20–1.21.11 · Fabric⬇ Download for 1.20–1.21.11 · NeoForge
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
