Pack setup

How should I set up Unbelievably Optimised for players and a server?

Dedicated server setup Match Unbelievably Optimised 1.0.1

Pack loader Fabric 0.19.2

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.

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 Unbelievably Optimised?

Unbelievably Optimised 1.0.1. Change the pack release and its contents or setup may change too.

33 mods in this pack file

The selected pack release is Unbelievably Optimised 1.0.1. That file is for Minecraft 1.21.11 with Fabric 0.19.2. 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.

At least 2gb of ram is recommended. If you can, add up to 4gb of ram, any more is wasted memory

If you don't know how to, watch this tutorial by MelonCube on Youtube.

Make sure vsync is off + frame limiter off. If you're lagging on a server turn your simulation and/or render distance down
