Fake FPS

A lightweight Fabric mod that reports a configurable fake FPS value instead of the real one. Purely cosmetic — your actual rendering, tick rate, and performance are never touched. Only the displayed number changes.

Features

Feature	Description
Custom FPS	Set any value from 30 to 5000
Randomize	Adds ± fluctuation (10–50) that updates twice a second — looks like a real counter
GUI	In-game settings screen via keybind (`'` by default) or Mod Menu
Broad compatibility	Vanilla F3, BetterF3, Sodium Extra, and any mod reading Minecraft's FPS
Multi-version	Single JAR supports Minecraft 1.21 → 1.21.11
Config persistence	Saved to `config/fakefps.json`

How it works

The mod intercepts `MinecraftClient.getCurrentFps()` and overwrites the `currentFps` field every frame. Whether a mod reads the getter or the field directly, it sees your spoofed value.

For Sodium Extra specifically, the mod also hooks into `FrameCounter.getSmoothFps()` so Sodium's own FPS display is spoofed too.

Requirements

Fabric Loader **0.18.1+**
Fabric API (any version for your Minecraft version)
Mod Menu (optional — recommended for easier config access)
