Quick answer

Which Optim+ release should I use?

Updated 4 months ago
Latest stable file Optim+ 1.0.1
Game version 1.21.8
Loader Fabric 0.17.3

Optim+ 1.0.1 is a complete pack release for 1.21.8 with Fabric 0.17.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 28 mods in this pack file.

Pack setup

How should I set up Optim+ for players and a server?

Use Optim+ 1.0.1 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 Optim+ 1.0.1
Dedicated server setup Match Optim+ 1.0.1
Pack loader Fabric 0.17.3

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 28
Client only 14
Server only 0
Not labelled 14

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 Optim+?

Optim+ 1.0.1. Change the pack release and its contents or setup may change too.

28 mods in this pack file

The selected pack release is Optim+ 1.0.1. That file is for Minecraft 1.21.8 with Fabric 0.17.3. It contains 28 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.
