OptiLithium Mod [1.19.2] is a general-purpose optimization mod for Minecraft which works to improve a number of systems (game physics, mob AI, block ticking, etc) without changing any behavior.


  • It works on both the client and server and can be installed on servers without requiring clients to also have the mod.
  • With the mod installed, you can see on average a 45% improvement to server tick times, resulting in a much leaner game.
  • Now with OptiLithium, you’re now able to use OptiFabric (Optifine) and lithium together.
