About this project
What does Prismium add?
Prismium
Vanilla+ performance optimization for Minecraft.
Prismium is a lightweight client-side performance mod focused on configurable rendering optimizations while keeping the vanilla Minecraft experience intact.
Features
Entity Culling — prevents entities outside the camera view from being rendered.
Distant Culling — controls how far away entities are rendered.
Particle Culling — reduces rendering of distant particles.
Particle Distance — configurable particle render distance from 1 to 32 blocks.
Dropped Item Distance — independently controls how far dropped items are rendered, from 1 to 128 blocks.
Persistent Configuration — settings are saved in
.minecraft/config/prismium.json.Custom Keybind — press G by default to open Prismium Settings. The key can be changed in Minecraft Controls.
Mod Menu Support — access Prismium Settings directly from Mod Menu.
Configuration
Prismium is designed to give players control over its optimizations instead of forcing fixed settings.
Settings can be changed directly in the Prismium Settings screen and are automatically saved to:
config/prismium.json
