Aetherium

Aetherium

Aetherium is a high-performance client-side Fabric mod for Minecraft 1.21.11, designed to maximize FPS while preserving visual quality and compatibility. It uses advanced distance and frustum culling for entities, block entities, and particles, and streamlines rendering for signs, beacon beams, clouds, weather, and animated textures. All features are fully configurable in-game, with detailed tooltips and recommended settings.
