Pack setup

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

Use Optimized Core Backport MC 1.21.2 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 Optimized Core Backport MC 1.21.2
Dedicated server setup Match Optimized Core Backport MC 1.21.2
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.

Referenced mods 24
Client only 13
Server only 2
Not labelled 9

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 Optimized Core?

Optimized Core Backport MC 1.21.2 on 1.21.2. The pack contents and setup notes below stay tied to that release.

24 mods in this pack file

The selected pack release is Optimized Core Backport MC 1.21.2. That file is for Minecraft 1.21.2 with Fabric 0.19.2. It contains 24 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.
