Incredibly Optimized
New 1.21 version out! Improves performance and optimization of your 1.20.4+ versions of Minecraft!
Quick answer
Which Incredibly Optimized release should I use?
io-1.20.6v1.2 is a complete pack release for 1.20.6 with Fabric 0.15.11. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 35 mods in this pack file.
Pack setup
How should I set up Incredibly Optimized for players and a server?
Use io-1.20.6v1.2 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.
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 Incredibly Optimized?
io-1.20.6v1.2. Change the pack release and its contents or setup may change too.
The selected pack release is io-1.20.6v1.2. That file is for Minecraft 1.20.6 with Fabric 0.15.11. It contains 35 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 Incredibly Optimized?
A simple modpack that improves the performance and graphics optimization of Minecraft!
Performance
This modpack has one of the highest performance than other modpacks.
Optimization Pack
This modpack is created for people to enjoy the best performance possible on Minecraft, without needing to buy a new PC or lose time downloading the mods and updating them over and over again.
Greatly Optimized
This modpack introduces several subtle enhancements that preserve the vanilla feel, including windowed fullscreen mode, fixes for bugs, and utilities to diagnose crashes.
Aim
This modpack focuses on performance and graphics enhancements. It is faster than OptiFine, thanks to modern performance mods like Sodium, Lithium, and others. It supports most OptiFine features, including shaders, connected textures, and zoom. It also includes features that allow you to experience Minecraft just as you remember it.
