The fastest and most compatible lag mod for Minecraft. Now available for both Forge and Fabric!
Introducing Uranium, a mod designed to take your Minecraft experience to a new level of challenge by introducing intentional lag. This mod makes the game unplayable, testing your patience and resilience.
Uranium was originally created as a joke to show friends how Minecraft used to run on my PC. Instead of describing bad performance, this mod recreates it by deliberately wasting processing power to cause lag, stuttering, and extremely low FPS.
The mod does not add new gameplay content, blocks, or items. It does not modify visuals, collect data, or perform any malicious actions, it simply makes the game run worse on purpose. The full source code is publicly available for transparency.
Uranium is intended for humor, experimentation, and challenge scenarios, such as joke modpacks or patience tests.
