Updated today

Best match for your filters fabric-26.2-0.0.1

Game version 26.2

Loader Fabric 0.19.3

fabric-26.2-0.0.1 is a complete pack release for 26.2 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 65 mods in this pack file.

Pack setup

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

Use fabric-26.2-0.0.1 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 fabric-26.2-0.0.1

Dedicated server setup Match fabric-26.2-0.0.1

Pack loader Fabric 0.19.3

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.

Plan the server requirements Read the Minecraft installation guide

Referenced mods 65

Client only 25

Server only 0

Not labelled 40

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?

fabric-26.2-0.0.1 on 26.2. The pack contents and setup notes below stay tied to that release.

65 mods in this pack file

The selected pack release is fabric-26.2-0.0.1. That file is for Minecraft 26.2 with Fabric 0.19.3. It contains 65 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?

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.
