The selected pack release is [Optimization] FPS Boost Pack [Fabric 1.21.11]-1.4.zip. That file is for Minecraft 1.21.11 with Fabric 0.18.2. It contains 21 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod.

Key Features & Unbeatable Advantages

🏆 The Best Performance Engine: Built on the superior Sodium/Iris foundation, this pack delivers the highest FPS gains, crushing the limits of the default game engine. Experience lightning-fast chunk loading and crystal-clear rendering.
🌍 Universal Server Compatibility: Works flawlessly on ANY server! Since all optimizations are client-side, you can jump onto Vanilla servers, Realms, Hypixel, or any other server without needing the pack installed there.
🧠 Superior Game Logic (High TPS): Lithium and Alternate Current ensure the server-side logic runs efficiently. Say goodbye to tick lag and enjoy stable, responsive gameplay, even during intense Redstone activity.
📉 Massive RAM Reduction: FerriteCore is utilized to aggressively optimize memory usage. This means fewer out-of-memory crashes and a lightweight Minecraft, perfect for background use or systems with less RAM.
🖼️ Full Shader Support: Integrated with Iris Shaders, you get the best of both worlds: ultra-high FPS from Sodium and the visual fidelity of your favorite shaders.
✨ Comprehensive Quality of Life: Includes essential client mods like Mod Menu, BetterF3, and WTHIT to make configuration easy and provide crucial in-game information without performance cost.
🚀 Lightning-Fast Startup: Smooth Boot and optimized resource loading ensure you spend less time waiting and more time playing.
