Lithium Modpack
Lithium Modpack (LiM) is a modpack thats purely focused in optimizing Minecraft.
For optimizing, it mainly uses Sodium, the mod that I consider the best for main optimization. Other mods added are for more options on sodium or optimizing specific things.
The main mods for optimization would be:
- Sodium
- Starlight
- More Culling
Examples of mods added for specific things:
- Clumps
- Language Reload
- Cull Leaves
- fast-ip-ping
This section will show frequently asked questions between users. This modpack is new, so there won't be any frequently asked questions for now.
Im gonna try to optimize every aspect possible to make this the best optimization modpack ever. Wish me luck!
How to install Lithium Modpack
With Millida Launcher
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 1.20.4–1.21.1 on Fabric automatically.
Launch the game
A profile with it appears in the launcher: click “Play”.
Manually
Download the modpack archive
In the version list above, pick the file LiM 1.7A.mrpack (331 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 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
