Lag Optimizer A lightweight, performance-focused Fabric modpack for Minecraft 1.21.1 designed to maximize your frame rates and make playing with friends completely seamless.

What this project does: This modpack brings together the absolute best open-source optimization mods available for the Fabric loader. It completely swaps out Minecraft's default rendering system with modern, high-efficiency engines that eliminate stuttering, lower memory usage, and keep your game running smoothly.

Why you should download it: If you struggle with low FPS, screen tearing, or server-connection lag, this pack is built for you. It includes:

Sodium & ImmediatelyFast: Massive boosts to your graphical frame rates and HUD rendering.

FerriteCore & Entity Culling: Drastically reduces RAM usage and stops the game from processing blocks or mobs you can't see.

Essential Mod: Allows you to host multiplayer worlds and invite your friends directly from your singleplayer menu without needing a paid server.

uku's Armor HUD: Adds a clean, minimalist display on your screen to track your current gear durability.
