Overview
More Culling is a client-side utility created by the developer FX. It belongs to the Libraries & APIs, Performance, and Utility & Quality of Life categories. The core idea is simple: stop drawing blocks, entities, or particles that the player can't see, which frees up rendering resources.
How it works
The mod rewrites several culling routines inside the game engine. By intercepting the visibility checks, it tells Minecraft to skip drawing objects outside the player’s view frustum or hidden behind other blocks. This change reduces the number of polygons and textures sent to the GPU each tick. The result is a smoother experience, especially in dense builds or large outdoor scenes.
Compatibility
More Culling runs on the Fabric, Quilt, and NeoForge mod loaders. Honestly, it is compatible with the following Minecraft versions: 26.3, 1.21.1, 1.21, 26.2, 26.1.2, 26.1.1, and 26.1. The mod works only on the client side; there's no server-side component. Cloth Config must be present for the configuration screen to appear.
Getting help
If you run into issues, you can file a bug report through the Modrinth project page. The author maintains a Discord server for real-time support and a wiki that covers what is culled, performance considerations, compatibility notes, and known bug fixes. This wiki also points to MoreCullingExtra, an optional add-on that adds extra culling options.
Related projects
FX also develops a handful of other optimization mods: MemoryLeakFix, which patches client and server memory leaks; Carpet-Fixes, a large collection of server-side bug fixes; Blanket, a set of client-side tweaks; and RailOptimization, which reduces lag from powered rails. These projects share a similar focus on improving the game’s stability and performance.
