About this Modpack
Uton — 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
- ✅ 100+ releases of testing for stable frametimes and minimal micro-stutters
- ✅ No extra features — just pure optimization, nothing more
