Optimizer Cat

Hello, this is an optimization modpack that I created using Fabulously Optimized.

Quick answer

Which Optimizer Cat release should I use?

Updated 1 year ago
Latest stable file Optimizer Cat 1.21.4
Game version 1.21.4
Loader Fabric 0.16.14

Optimizer Cat 1.21.4 is a complete pack release for 1.21.4 with Fabric 0.16.14. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 42 mods in this pack file.

Pack setup

How should I set up Optimizer Cat for players and a server?

Use Optimizer Cat 1.21.4 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 Optimizer Cat 1.21.4
Dedicated server setup Match Optimizer Cat 1.21.4
Pack loader Fabric 0.16.14

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.

Referenced mods 42
Client only 30
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 Optimizer Cat?

Optimizer Cat 1.21.4 . Change the pack release and its contents or setup may change too.

42 mods in this pack file

The selected pack release is Optimizer Cat 1.21.4 . That file is for Minecraft 1.21.4 with Fabric 0.16.14. It contains 42 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 Optimizer Cat?

This modpack is based on Fabulously Optimized and has been customized to enhance performance and gameplay in Minecraft 1.21.1 using Fabric. The main focus is on optimizing the game to increase FPS and reduce resource usage. Replace this with a description

Key Features:

  • Performance Optimization: Mods like Sodium, Lithium, FerriteCore, Entity Culling, and Dynamic FPS work together to make the game run smoother and use less memory and CPU.

  • Visual Enhancements & Compatibility: Includes shader support with Iris, dynamic lighting, custom textures, and visual improvements (Continuity, CIT Resewn), which are optional and focused on aesthetics.

  • Configuration and Usability: Includes APIs and tools to ease mod management and settings (Cloth Config API, Mod Menu, YOSBR).

  • Interface and Chat Improvements: Adds features like extended chat history and better advancement and menu displays.

  • Note about Texture Packs and Visual Mods:
    Texture packs and visual mods such as FabricSkyBoxes (Nuit), Animatica, OptiGUI, and others are included but fully optional. Their purpose is to enhance the visual experience without impacting base performance. You can choose to use them or not based on your preference.

This modpack has been tested on a computer with the following specs. I recommend not playing if you experience FPS drops, as I do too, but I still want to play:

  • CPU: Intel(R) Celeron(R) N4500 @ 1.10GHz

  • RAM: 4GB (3.8GB usable)

  • Storage: Generic MMC128

  • GPU: Intel(R) UHD Graphics

  • Wifi: Intel(R) Wireless-AC 9560
