UltraBoost — The Peak of Minecraft Performance
UltraBoost is a lightweight, Fabric-based pack built for pure speed. No filler, no clutter — just the highest possible FPS.
Real performance results: UltraBoost reached up to 260 FPS, while other popular optimization packs struggled to hit 190-230 FPS. The difference is massive.


What you get:
- Faster loads, smoother rendering, stable ticks
- Zero stutter and reduced latency
- Memory-efficient and network-friendly
- Perfect for low-end PCs and servers
- Clean vanilla feel — no unnecessary mods
This pack beats every other optimization pack tested. Right now, it’s the most optimized Minecraft modpack in the world — built for players who want the absolute maximum from their game.
UltraBoost — when every frame matters.

UltraBoost 설치 방법
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 1.21.11–26.1 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 UltraBoost 26.1.mrpack (29 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.
On a server
Use the “To server” button
On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
Invite friends: they install the same modpack
To join the server, every player needs the same modpack version.
