About this Modpack

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

Frequently Asked Questions

Ultimately Optimized+ server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong forge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Ultimately Optimized+ server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to Ultimately Optimized+ without conflicts?

Yes, but check compatibility: only use mods for the same loader (forge) and same Minecraft version (1.21). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

Ultimately Optimized+ server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
