Quick answer

Which RMC Optimization release should I use?

Updated 10 days ago

Latest stable file RMC Optimization 1.0.4

Game version 1.21.11

Loader Fabric 0.20.1

RMC Optimization 1.0.4 is a complete pack release for 1.21.11 with Fabric 0.20.1. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 52 mods in this pack file.

Pack setup

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

Use RMC Optimization 1.0.4 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 RMC Optimization 1.0.4

Dedicated server setup Match RMC Optimization 1.0.4

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 52

Client only 29

Server only 1

Not labelled 22

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 RMC Optimization?

RMC Optimization 1.0.4. Change the pack release and its contents or setup may change too.

52 mods in this pack file

The selected pack release is RMC Optimization 1.0.4. That file is for Minecraft 1.21.11 with Fabric 0.20.1. It contains 52 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.
