culling +

The mod removes from the render pass geometry that cannot be seen anyway: hidden entities, distant particles, underground clouds and faces hidden behind other blocks. Sounds that would be redundant in those spots are skipped too, and glass faces that never show are not drawn. Because it only changes what the client renders, it is a client-side only mod and a server needs nothing from it.

The mod is available for Fabric only, in 12 release versions 1.21 – 1.21.11, with 1.0.3 for 1.21.11 as the latest file. Changing its settings needs Mod Menu, which opens the configuration screen. The code is not open source, and the project is released under the CC0 1.0 Universal license.
