Potassium

Potassium is a Fabric mod that improves rendering safety, frame pacing, and stability fixes. It maintains vanilla visual feedback while reducing redundant rendering in particle-heavy scenes, UI updates, map changes, and the 26.x renderer paths. As a lightweight client-side mod, Potassium enhances areas of Minecraft not heavily optimised by other mods. Instead of replacing the rendering engine or rewriting major systems, it targets small inefficiencies in UI updates, animations, particles, and background systems.

It is designed to work alongside other popular optimisation mods such as Sodium and Lithium.

✨ Features

HUD Render State Throttle

Reduces redundant HUD processing when values haven’t changed.

Health, hunger, and status effects skip state extraction for up to 3 frames when unchanged.
Prevents unnecessary UI recalculation.
Status-effect overlay extraction is skipped when the same effect state is rebuilt multiple times in the same tick. Prevents unnecessary UI recalculation without causing HUD flashing.
