Zer0

Ultra-minimalist rendering optimization for Fabric. Strips away unnecessary visual pipeline passes to maximize FPS and eliminate render overhead.

Overview

Zer0 is a lightweight, client-side optimization mod for players who want maximum frame rates and a completely clutter-free view. By directly targeting and bypassing heavy visual rendering passes at the Mixin level, Zer0 eliminates CPU and GPU cycles spent on non-essential graphics effects.

Features

• ☁️ No Cloud Rendering — Completely bypasses the cloud rendering pass (CloudRenderer) to save geometry and draw calls.
• 🌫️ Zero Fog — Overrides FogRenderer to clear atmospheric fog entirely for crystal-clear vision across any render distance.
• 💡 Disabled Lightmap Updates — Bypasses dynamic lightmap recalculations (Lightmap), stopping unnecessary frame-by-frame light updates.
• ⚡ Zero Bloat — No external dependencies beyond Fabric API, no configuration menus, and zero background processing overhead.
