Quick answer

Which Ultra Optimized X release should I use?

Updated 5 months ago
Latest stable file Ultra Optimized X 1.1.3
Game version 1.21.11
Loader Fabric 0.18.4

Ultra Optimized X 1.1.3 is a complete pack release for 1.21.11 with Fabric 0.18.4. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 33 mods in this pack file.

Pack setup

How should I set up Ultra Optimized X for players and a server?

Use Ultra Optimized X 1.1.3 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Ultra Optimized X 1.1.3
Dedicated server setup Match Ultra Optimized X 1.1.3
Pack loader Fabric 0.18.4

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Referenced mods 33
Client only 14
Server only 2
Not labelled 17

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Ultra Optimized X?

Ultra Optimized X 1.1.3. Change the pack release and its contents or setup may change too.

33 mods in this pack file

The selected pack release is Ultra Optimized X 1.1.3. That file is for Minecraft 1.21.11 with Fabric 0.18.4. It contains 33 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

About this project

What kind of pack is Ultra Optimized X?

TITLE
The main purpose of this modpack is to provide a stable and useful template for building your own optimized Minecraft experience.

YOU MAY NEED TO TWEAK AND TUNE BASED ON YOUR SYSTEM

The pack works well out of the box, but for a better experience i recommend all to try out different settings and functions to see what works best. Better yet, make your own copy of the pack and change out the mods themselves to your own liking.

The focus of this pack is pure and raw performance, making sure that you will be able to run Minecraft on any system. This is ideal for laptop gamers, or gamers with low-end hardware. This was itself the inspiration for making a performance modpack, seeing as i myself want to play Minecraft on-the-go.
