About

A Fabric *.21.11 client-side performance mod that squeezes extra FPS from Minecraft's rendering engine. Implements fast-math lookup tables (replacing JDK sin/*** with pre-baked 65 536-entry arrays), aggressive entity distance + volume culling (skip rendering tiny far-away entities the frustum check misses), per-frame chunk-rebuild budgeting to prevent tick spikes when many sections go dirty, and fast inverse square root via the Quake III bit-hack through raw float↔int conversion.
