# Rubidium

**Rubidium** is a lightweight client-side Minecraft utility focused on improving the way performance information is presented in-game.

The mod adds a small **Rubidium Modifier** entry to the vanilla F3 debug screen and provides an alternative FPS display designed to make high-FPS setups easier to monitor.

## Features

* 📊 Alternative FPS display on the vanilla F3 screen
* 🖥️ Takes your monitor refresh rate into account
* ⚙️ Lightweight client-side implementation
* 🔴 Clearly identifies Rubidium's modified debug information
* 🧩 Designed to work alongside other client-side mods
* 🚫 Does not modify server gameplay or mechanics

## How It Works

Rubidium integrates with Minecraft's existing debug overlay rather than replacing the entire F3 screen.

The FPS value is presented using information from Minecraft's client and display configuration, with behavior adjusted according to the configured monitor refresh rate and frame-rate limit.

## Compatibility

* **Minecraft:** 1.21.11
* **Loader:** Fabric
* **Side:** Client
* **Fabric API:** Required

Rubidium is intended to be used with other client-side mods and does not need to be installed on a server.

## Development

Rubidium is an experimental project focused on client-side Minecraft modifications and performance-related experimentation.

More features and configuration options may be added in future versions.
**Contains Code Made Using AI!!**
