Just Optimized
Speeds up the game performance by a lot for both client and server
Quick answer
Which Just Optimized release matches 1.18.1?
Just Optimized is a complete pack release for 1.18.1 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. 21 mods in this pack file.
Pack setup
How should I set up Just Optimized for players and a server?
Use Just Optimized 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.
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.
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 Just Optimized?
Just Optimized on 1.18.1. The pack contents and setup notes below stay tied to that release.
The selected pack release is Just Optimized. That file is for Minecraft 1.18.1 with Fabric 0.20.1. It contains 21 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 Just Optimized?
The modpack tries to optimize the game in a way to keep the vanilla parity and optimizations as high as possible. I do my best in updating the modpack and keeping things as clean as possible.
