Quick answer

Which OptiBoost release should I use?

Updated 11 months ago
Latest stable file OptiBoost 1.21.5 Forge
Game version 1.21.5
Loader Forge 55.1.0

OptiBoost 1.21.5 Forge is a complete pack release for 1.21.5 with Forge 55.1.0. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 12 mods in this pack file.

Pack setup

How should I set up OptiBoost for players and a server?

Use OptiBoost 1.21.5 Forge 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 OptiBoost 1.21.5 Forge
Dedicated server setup Match OptiBoost 1.21.5 Forge
Pack loader Forge 55.1.0

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 12
Client only 0
Server only 0
Not labelled 12

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 OptiBoost?

OptiBoost 1.21.5 Forge. Change the pack release and its contents or setup may change too.

12 mods in this pack file

The selected pack release is OptiBoost 1.21.5 Forge. That file is for Minecraft 1.21.5 with Forge 55.1.0. It contains 12 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.

About this project

What kind of pack is OptiBoost?

The reason I developed this project was because mine and others were unable to play Minecraft due to their poor computers. So, I came up with an idea and developed this project. More projects will be coming in the future, and this project will continue to receive updates.
