# ⚡ 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.
