Quick answer

Which Optimization Foundation release should I use?

Updated 14 days ago
Latest stable file neoforge-1.21.1-0.3.2
Game version 1.21.1
Loader NeoForge 21.1.265

neoforge-1.21.1-0.3.2 is a complete pack release for 1.21.1 with NeoForge 21.1.265. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. For this loader, use Java 21. 84 mods in this pack file.

Pack setup

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

Use neoforge-1.21.1-0.3.2 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 neoforge-1.21.1-0.3.2
Dedicated server setup Match neoforge-1.21.1-0.3.2
Pack loader NeoForge 21.1.265
Java version Java 21

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 84
Client only 24
Server only 0
Not labelled 60

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 Optimization Foundation?

neoforge-1.21.1-0.3.2. Change the pack release and its contents or setup may change too.

84 mods in this pack file

The selected pack release is neoforge-1.21.1-0.3.2. That file is for Minecraft 1.21.1 with NeoForge 21.1.265. This NeoForge setup needs Java 21. It contains 84 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 Optimization Foundation?

Banner

Optimization Foundation is a performance modpack that is designed for other creators, and for players who want a smooth vanilla minecraft experience.

I created this pack because I was tired of getting around 20 FPS while playing modpacks on a low-end PC or laptop.

My goal is to build a perfect performance foundation so anyone can enjoy larger modpacks with smoother gameplay, and so that I can play a big modpack without lag for once.

Features:

  • Higher FPS
  • More stable tick rates
  • Faster chunk generation
  • Fixes for bugs, crashes, and memory leaks
  • Faster game startup
  • Faster structure and biome locating

Note:

  • Bug reports, suggestions, and feedback can be posted in the comments for now.
  • Feel free to use this as a foundation, you don't have to credit me or ask for permission.

This modpack aims to include every optimization used in large modpacks. If you think something is missing or can be improved, please let me know.
