Ultimately Optimized

Enjoy the plain old vanilla Minecraft, but with performance and FPS improvements.

This modpack adds performance and FPS improvements and nothing more, trying to replicate the base game without many additions or gameplay changes.

Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.
Click “Install” on this page
The launcher opens and installs the modpack for Minecraft 1.8–1.21 on Fabric, Forge, NeoForge or Quilt automatically.
Launch the game
A profile with it appears in the launcher: click “Play”.

Download the modpack archive
In the version list above, pick the file Ultimately Optimized.mrpack (2 KB).
Import it into a launcher
A launcher that supports modpacks (Millida Launcher, Prism) takes the archive via “Add modpack”, then “From file”. No need to unpack it yourself.
Allocate memory
Modpacks need more memory than the plain game: set 4–6 GB in the profile settings.

Minecraft 1.21 runs on Java 21: with a different Java version the game may close right after launch.
