MC-Optimization-Guide Continuation

This repository was created on 13/01/26 after the original creator’s account was deleted.
All credit goes to Radk6.
This fork (try) keeps the guide active after the original repo was deleted. This repository uses the latest version of the original repository (fortunately, I synced my fork the day before its deletion). If the original creator resumes activity, this repository will be discontinued in their favor. I will try to maintain it if the original creator does not return.

MC-Optimization-Guide

The end-all, be-all optimization guide for various Minecraft versions.

NOTE: This guide only covers performance mods that are deemed "necessary", so duplicate mods that do the same thing (eg. Rubidium and Embeddium, Radon and Starlight, etc.) won't be included.

It also takes a fairly minimalist approach. This means that while there may be a way to squeeze out a couple fps more with additional mods, the mods listed here should be more than enough for smooth and lag-free gameplay.

Inspired by UsefulMods and various Reddit threads, as well as my own testing.

Q: Why isn't version x.y.z supported?
