Logically Optimized
(1.19.4-26.3) Introducing Logically Optimized! A lightweight performance modpack for vanilla-style Minecraft with faster loading, smoother gameplay, shader support, and essential QoL features.
Quick answer
Which Logically Optimized release matches 1.21.9?
Logically Optimized 1.21.9 v2.8.9 is a complete pack release for 1.21.9 with Fabric 0.19.2. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 34 mods in this pack file.
Pack setup
How should I set up Logically Optimized for players and a server?
Use Logically Optimized 1.21.9 v2.8.9 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 Logically Optimized?
Logically Optimized 1.21.9 v2.8.9 on 1.21.9. The pack contents and setup notes below stay tied to that release.
The selected pack release is Logically Optimized 1.21.9 v2.8.9. That file is for Minecraft 1.21.9 with Fabric 0.19.2. It contains 34 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 Logically Optimized?

Introducing Logically Optimized!
The Minecraft modpack includes everything you need! Enjoy smooth and enjoyable gameplay that keeps you engaged, extremely quick loading times. This modpack is for overall performance but also adds shader support, zooming features, adding resource packs, and shaders without quitting while you're playing the game.
You can use it in any world, any server!
Logically Optimized: It doesn't add extra content to the game, ensuring compatibility with nearly any world or server.
Performance
Logically Optimized is faster than other modpacks because it includes modern performance mods like Sodium and Lithium. And optimized the config file. These mods are safe to use in your worlds and can significantly improve speed on any device.
More than 300 FPS In RTX Laptop/PC (the RTX 30-50 series laptops/PCs can get guaranteed over 500 FPS)
150+ FPS In GTX Laptop/PC (maybe some of them are worse than that, and some of them are actually better than that a lot by getting over guaranteed 300 FPS)
OptiFine Features
Logically Optimized supports most OptiFine features, such as shaders, connected textures, and zoom!
Up to date
Logically Optimized receives quick updates and is one of the first modpacks to upgrade to newer versions of Minecraft.
Updating the modpack is simple and will retain your mod settings whenever possible.
Installation!
- Add the mods in the "/mods" folder.
- Put the config file in the ".minecraft/config" folder.
- Enjoy the game
Note: it's important to add options.txt; it gives you a better performance than what you think.
You need to remove the following mods below if you're using the Lunar client:
- 1. Modernfix.
- 2. C2ME.
- 3. ImmediatelyFast.
Feather client doesn't need to remove any mod from the modpack
labymod, and other client launchers, you need to remove some mods to work.
