Pack setup

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

Use Quantum Optimized 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 Quantum Optimized

Dedicated server setup Match Quantum Optimized

Pack loader Fabric 0.20.1

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 15

Client only 8

Server only 1

Not labelled 6

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 Quantum Optimized?

Quantum Optimized. Change the pack release and its contents or setup may change too.

15 mods in this pack file

The selected pack release is Quantum Optimized. That file is for Minecraft 26.3 with Fabric 0.20.1. It contains 15 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 Quantum Optimized?

Quantum Optimized

By carefully selecting and configuring the best performance mods on Fabric, it eliminates annoying spikes and stutters, giving you a silky-smooth Minecraft experience where high FPS actually matters.

Features:

Zero Stutter Focus: Prioritizes frame time stability over inflated, unstable numbers.

Silky Smooth Gameplay: Enjoy buttery-smooth movement, chunk loading, and combat without unexpected freezes.
