Simple World Anti-Lag
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.


📑 Information
A lag-cleaner for your Minecraft worlds, fully optimized without consuming ticks by running asynchronously. This data pack was specially designed to improve game performance in your saturated worlds, reducing tick consumption by junk entities and some blocks without affecting your farms.
😛 Some features:
- Despawn junk entities every five minutes (Adjustable to 3 and 10 minutes), including useless entities like bats, squid drops waiting to be despawned and some monsters out of nearby chunks (Excluding pet/farm entities and entities generated by other data packs), fixing the Minecraft's most common saturations in large worlds or with many entities.
- You can change the format of the cleaning warning messages or even change the time each cleaning will be performed using /function antilagplus:settings (Requires administrator if you are in a server).
- Does not consume ticks as it works asynchronously, it only releases more.
- If you are not English speaking, you can change the language of the cleaning messages to Spanish using /function antilagplus:settings! - Si eres hispanohablante, ¡puedes cambiar el idioma de los mensajes de limpieza usando /function antilagplus:settings!
- It's compatible with any other data pack or mod.
