Entity Culling Mod (1.21.8, 1.20.1) – Boost FPS by Hiding Hidden Entities

Minecraft’s default rendering engine draws all nearby entities even those hidden behind walls or terrain which can waste valuable resources. The Entity Culling Mod (1.21.8, 1.20.1) fixes that with smart visibility detection. It uses asynchronous path-tracing to determine whether a tile entity or mob is actually visible to the player’s camera. If not, it skips rendering them entirely just like how Minecraft already skips objects behind the player. The result? A significant FPS boost with no visual compromise.

Features:

Smart entity/tile culling with async path-tracing
Calculates visibility by tracing paths from the camera to nearby entities/tile entities using additional CPU threads, ensuring only visible objects are rendered.
Significantly improves performance
Reduces GPU load by preventing hidden objects (e.g., mobs behind walls, machines in another room) from being drawn.
Culling range of 128x128x128 blocks
Checks all entities and tile entities within 64 blocks in each direction from the player. Anything beyond that is automatically skipped similar to Minecraft’s “Entity Distance” setting.
Works automatically in the background
No need to configure anything. The mod activates right away and runs seamlessly with no in-game interface required.
Multiloader support
Compatible with Fabric, Forge, and NeoForge, making it easy to include in any modpack setup.
Lightweight and efficient
Designed to complement other performance mods without conflicting or overlapping with them.

Why use Entity Culling Mod?

Minecraft renders way more than it needs to especially in large bases, farms, or modded setups with machines and storage blocks. By skipping the rendering of entities you physically can’t see, Entity Culling cuts down GPU workload and improves frame rates, especially on mid-range or lower-end systems.

It’s an ideal companion to mods like Sodium, Lithium, and Dynamic FPS, and can even boost FPS in heavy modpacks without any config or setup.

If you’re tired of lag spikes near complex builds or modded machinery, this mod is a must-have.
