Easy assembly of mods to improve performance without changing the vanilla game. It works everywhere and is thoroughly tested with old hardware before…

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

# ⚡ UO — Pure Performance, Zero Compromise

 

**Uton** is an optimization modpack with one goal: **maximum FPS without touching vanilla.**

No visual changes. No broken mechanics. Just a faster, smoother Minecraft.

 

---

 

## 🎯 What makes Uton different?

 

Most optimization packs either change how the game looks, break vanilla behavior, or only support one mod loader. **Uton does none of that.**

 

- ✅ Vanilla graphics preserved — no downgraded textures or lighting

- ✅ Vanilla logic untouched — redstone, mobs, and mechanics work exactly as Mojang intended

- ✅ 90+ releases of testing for stable frametimes and minimal micro-stutters

- ✅ No extra features — just pure optimization, nothing more

## 🏗️ Pack Architecture

 

Uton is not just a collection of mods thrown together. Every version is built on a defined architecture — a carefully selected and tested set of mods that work together as a system.

 

| Architecture | Versions | Description |

|---|---|---|

| **LPA-1** | 1.7.10, 1.8.9, 1.12.2 | Legacy Pack Architecture. Built for old Forge environments where modern optimization mods don't exist. Stable enough for daily use. |

| **MPA-3** | 1.16.5–1.21.11 | Mod Pack Architecture. Modern optimization — Sodium, Lithium, and compatible companions. Covers a wide range of versions with consistent performance. |

| **MPA-4** | 1.20.1–1.21.11, 26.x | Current generation architecture. Expanded mod selection including newer discoveries like Noisium and Signs Faster. More powerful optimization than MPA-3 with better balanced FPS. Replaces MPA-3 on supported versions. |

 

> Each architecture is independently tested. Updating Uton to the latest release for your version and loader is always recommended to get the current architecture.
