Quick answer

Which Optimization Unleashed release should I use?

Updated yesterday
beta file Optimization Unleashed-1.0.0.zip
Game version 1.20.1
Loader Forge 47.4.10

Optimization Unleashed-1.0.0.zip is a complete pack release for 1.20.1 with Forge 47.4.10. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 43 mods in this pack file.

Pack setup

How should I set up Optimization Unleashed for players and a server?

Use Optimization Unleashed-1.0.0.zip 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 Optimization Unleashed-1.0.0.zip
Dedicated server setup Match Optimization Unleashed-1.0.0.zip
Pack loader Forge 47.4.10

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.

Plan the server requirements Read the Minecraft installation guide
Referenced mods 43
Client only 15
Server only 0
Not labelled 28

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 Optimization Unleashed?

Optimization Unleashed-1.0.0.zip. Change the pack release and its contents or setup may change too.

43 mods in this pack file

The selected pack release is Optimization Unleashed-1.0.0.zip. That file is for Minecraft 1.20.1 with Forge 47.4.10. It contains 43 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 Optimization Unleashed?

Optimization Unleashed

This modpack is designed for optimal performance, with all unnecessary mods removed!

It’s packed with optimizations for both the server and client, with a primary focus on client-side performance.

Thanks to Luxium, you can enjoy a beautiful Minecraft world while maintaining high FPS.

Features

  • Highly optimized for both low-end and high-end systems
  • Beautiful graphics with high FPS, powered by Luxium
  • Fast startup time — less than 20 seconds on a properly configured system
  • Extremely low memory usage — capable of running with as little as 1 GB of RAM

Important

This modpack contains many alpha and early-development mods. As a result, you may encounter crashes, bugs, or unexpected behavior.

While the modpack can run with as little as 1 GB of RAM, this is not recommended. For a smoother experience, allocating more RAM is recommended.

If you encounter a bug or a compatibility issue with another mod, please report it in the comments! Your reports will help improve the modpack.

Oculus is NOT compatible with this modpack. Luxium is incompatible with Oculus, so please do not install Oculus alongside this modpack.
