Ultimately Optimized+
A very highly optimized modpack made to continue the old ultimately optimized modpack
Quick answer
Which Ultimately Optimized+ release matches 1.20.6?
Ultimately Optimized+ 1.20x Fabric is a complete pack release for 1.20.6 with Fabric 0.18.4. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 22 mods in this pack file.
Pack setup
How should I set up Ultimately Optimized+ for players and a server?
Use Ultimately Optimized+ 1.20x Fabric 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 Ultimately Optimized+?
Ultimately Optimized+ 1.20x Fabric on 1.20.6. The pack contents and setup notes below stay tied to that release.
The selected pack release is Ultimately Optimized+ 1.20x Fabric. That file is for Minecraft 1.20.6 with Fabric 0.18.4. It contains 22 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 Ultimately Optimized+?
Ultimately Optimized+
A performance modpack made to make Minecraft run better — from 1.7.10 and 1.8.9 all the way up to the latest versions.
It’s clean. It’s fast. It just works.
What it does
- Boosts your FPS — no complicated setup
- Works on older PvP versions like 1.7.10 & 1.8.9
- Supports modern versions with Sodium, Iris, Vulkan, etc.
- Supports most (Mod) loaders such as Fabric (Sodium & Vulkan Support), Forge, Neoforge and Quilt
- Client-side only (probably) — safe for multiplayer
- Feels like vanilla (just smoother)
- Shader ready if you want that extra touch
Modloaders Version Support
- Fabric Support: 1.16.5 and Above
- Forge Support: 1.7.10 and Above
- NeoForge Support: 1.21.1 and Above
- Quilt Support: 1.18.2 and Above
Why “+”?
The + stands for a multi working modpack with:
- continuation of old project: Ultimately Optimized
- Pre-configured settings for less lag and better stability
- Ready to be customized or left as is
Built for:
- PvPers who still plays and enjoys 1.8.9
- Players on low-end hardware
- People who hate stutter
- Anyone who wants Minecraft to run like it should
- But main focus is 1.16.5 and above
Want even more FPS?
Ultimately Optimized+ already boosts your performance out of the box — but if you're looking to squeeze out every last frame, we recommend adding a few extra mods (some available outside Modrinth):
- Legacy Versions
- Optifine (a lil more fps boost if needed)
- Modern Versions
- Coming soon...
These mods pair perfectly with the pack and can push your performance even further.
Quick FAQ
Can I add mods?
Yep. This is just the base — tweak it how you like.
Does it support shaders?
Definitely. Iris (or Optifine on old versions) has you covered.
What about servers?
Fully client-side. Join any vanilla or modded server, no problem.
Ultimately Optimized+
No bloat. No weird mods. Just better performance.
Warning: Nvidium is experimental so if you have an nvidia gpu and cant launch minecraft disable Nvidium
