About

Depending on your game version, Minecraft loads some chunks when you create your world. Sometimes, these chunks are always loaded in the background. Either way, whether these chunks being loaded is a one-time performance slowdown, or a constant performance penalty, most players don't need any of these chunks. This mod completely disables unneeded chunks in the game.

Note: Unneeded chunks are sometimes used by farms and technical contraptions. If you'll need these chunks, you can always delete the mod later to re-enable these chunks.

Versions

Version	Effect	Note

1.20.5-1.21.8	Low	A 5x5 area of spawn chunks won't be loaded constantly in the background.
1.8-1.20.4	Extreme	A 21x21 area of spawn chunks won't be loaded constantly in the background.

Q: This mod doesn't speed up anything.
A: The effect may not be noticeable on high-end PCs. This mod is designed primarily for low-end devices. Nevertheless, there is a video.

Q: How to force-load chunks if the spawn chunks have been removed?
A: If you really need to force-load chunks, load individual chunks with the /forceload command in 1.13 or newer. For older versions, you can search for some mod that force-loads chunks.

Q: It says Ksyxis: No Mixin found.
A: If you're using Forge 1.15.2 or older, you may need to install MixinBootstrap, MixinBooter, UniMixins, or any other Mixin provider of your choice. If you're using Forge 1.16 or newer, or any version of Fabric/NeoForge/Quilt/Ornithe, you don't need to install anything, and this is a bug.
