Fubric API
Fubric API is a Forge and NeoForge library for Minecraft 1.20.1 whose author describes it as a deliberately ineffective performance mod.
What it does
The author's description says the mod lowers frame rates and slows world loading, which is the opposite of what performance mods normally aim for. The text is written as a joke, so the claims are not measurements and should not be taken as tested behavior. It runs on the client only, so the server does not need it. Files are published for Forge and NeoForge for 1.20.1 only. Both have a 1.0.0 file dated 2025-01-01, and the mod is released under All rights reserved, so it is not open source.
Key features
Lowers frame rates
The author says the mod caps or reduces frame rates, so the game runs less smoothly than it would otherwise.
Slows world loading
According to the description, worlds take longer to load, adding delay to the loading screens.
Adds stutter and lag
The author text claims the mod increases lag spikes and instability, which is described as its purpose.
