# ⚡ Tachyo Optimized — Next-Gen Minecraft 26.3 Modpack

**Tachyo Optimized** is an all-in-one performance, visual parity, and quality-of-life modpack built for **Minecraft 26.3 (Fabric)**. 

While popular packs like *Fabulously Optimized* focus only on light visual tweaks, **Tachyo Optimized** pushes engine boundaries by integrating true multi-threaded chunk generation (**C2ME**), entity/packet optimization (**VMP**), full OptiFine feature parity, and rich vanilla-friendly QoL improvements.
