Updated 5 months ago
Best match for your filters Ultimately optimized+ 1.8.9 Forge
Game version 1.8.9
Loader Forge 11.15.1.2318

Ultimately optimized+ 1.8.9 Forge is a complete pack release for 1.8.9 with Forge 11.15.1.2318. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 10 mods in this pack file.

Pack setup

How should I set up Ultimately Optimized+ for players and a server?

Use Ultimately optimized+ 1.8.9 Forge 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.

Plan the server requirements Read the Minecraft installation guide
Referenced mods 10
Client only 5
Server only 3
Not labelled 2

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+ 1.8.9 Forge on 1.8.9. The pack contents and setup notes below stay tied to that release.

10 mods in this pack file

The selected pack release is Ultimately optimized+ 1.8.9 Forge. That file is for Minecraft 1.8.9 with Forge 11.15.1.2318. It contains 10 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
  1. Optifine (a lil more fps boost if needed)
  • Modern Versions
  1. 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
