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

Client instance Install Optimized Core Backport MC 1.20.3
Dedicated server setup Match Optimized Core Backport MC 1.20.3
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 25
Client only 12
Server only 2
Not labelled 11
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 1.20.3 on 1.20.3. The pack contents and setup notes below stay tied to that release.
The selected pack release is Optimized Core Backport MC 1.20.3. That file is for Minecraft 1.20.3 with Fabric 0.19.2. It contains 25 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.
