Lightning Optimizer (FPS Boost & Lag Fix / Performance Utility)

Lightning Optimizer is a lightweight, open-source Minecraft performance mod designed to improve frame stability, reduce lag spikes, and optimize overall client-side performance.

It focuses on targeted optimizations rather than rewriting core game systems, making it compatible with most modpacks and other optimization mods.

If you experience micro-stutters, FPS drops during gameplay, or heavy performance issues in certain situations, this mod helps smooth out gameplay without requiring any configuration.
