Loader Forge 47.4.20

Pack setup

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

Use Ultimate Optimization 1.1.0 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 Ultimate Optimization 1.1.0
Dedicated server setup Match Ultimate Optimization 1.1.0
Pack loader Forge 47.4.20

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 18
Client only 11
Server only 3
Not labelled 4

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 Ultimate Optimization?

Ultimate Optimization 1.1.0. Change the pack release and its contents or setup may change too.

18 mods in this pack file

The selected pack release is Ultimate Optimization 1.1.0. That file is for Minecraft 1.20.1 with Forge 47.4.20. It contains 18 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 Ultimate Optimization?

Ultimate Optimization

Ultimate Optimization is a Forge 1.20.1 optimization modpack designed to deliver the best possible performance while keeping Minecraft smooth, stable, and fully compatible with large modpacks.

This pack combines modern optimization technologies to improve rendering, memory usage, chunk loading, entity processing, and overall game performance. It significantly reduces lag, micro-stuttering, and long loading times while increasing FPS by up to 2x depending on your hardware and installed mods.

Unlike many “FPS packs” that only focus on graphics settings, Ultimate Optimization improves both client and server performance. The modpack was carefully built to stay lightweight, stable, and compatible with most Forge modpacks.
