Superfast
Superfast is the fastest and best performance optimization modpack there is! Superfast includes amazing QoL features like Fullbright and zoom, which are both ideal for content creators. Superfast almost triples your FPS in all situations and pretty much never lags! Superfast also includes support for shaders, meaning that all you have to do switch on your shaders, and play! You can even join any server with Superfast without getting kicked or banned!
DISCLAIMER:
Not all features are available on Quilt, use Fabric for maximum compatibility/performance. This includes zooming functionality and Fullbright. Non-Fabric loader compatability is being discontinued.
How to install Superfast
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 1.21 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 Superfast 2.2.0.mrpack (4.6 MB).
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.
