Phosphor is a Fabric mod for Minecraft that optimizes the game's lighting engine to dramatically improve performance and fix related bugs. It works on both client and server, and servers can run it without clients installing the mod.
Use cases
- reduce Minecraft server lag from lighting calculations
- improve Minecraft client FPS caused by the lighting engine
- optimize light updates on a Fabric modded server
- fix lighting bugs in Minecraft without changing vanilla behavior
- speed up chunk lighting when exploring new areas
When to choose
- you run a Fabric modded client or server and want lighting performance gains
- you want vanilla-identical lighting behavior with fewer CPU cycles spent
- you need a server-side optimization that clients don't need to install
When to avoid
- you play vanilla without mod loaders
- you use mods that drastically rewrite the lighting engine
- you need a mod actively updated for the latest Minecraft versions
