Fake Fps+

Fake your FPS with ease — static or random values, configurable in-game. Works with Sodium, Iris, and any FPS counter mod.

Overview

Fake Fps+ is a lightweight Fabric mod that intercepts Minecraft's FPS display and replaces it with a value of your choosing. Whether you're recording content, streaming, benchmarking, or just want consistent FPS numbers on screen, this mod gives you full control with zero performance impact.

Features

Configurable FPS Values: Choose between a static FPS number or a randomized range that updates naturally once per second.
In-Game GUI (F6): Press F6 to open a clean configuration screen where you can toggle the mod, switch between static/random mode, and adjust values — all without leaving the game.
Quick Toggle (F7): Press F7 to instantly enable or disable the mod mid-game.
Persistent Settings: Your configuration is saved to a JSON file and automatically restored on next launch — set it once and forget it.
No Performance Hit: The mod simply intercepts the FPS counter output. It doesn't inject frames, cap framerates, or affect rendering in any way.
Works With Everything: Compatible with Sodium, Iris, OptiFine (via F3), Lunar Client FPS counter, and any other mod that reads Minecraft's built-in FPS counter.

How It Works

Fake Fps+ uses a single Mixin to intercept Minecraft.getCurrentFps() and return your configured value. When disabled, it passes through the real FPS
unchanged. In random mode, a new value is generated once per second with a small smoothing window to avoid jarring jumps.

Controls

┌─────┬────────────────────────────────────────────────────────────┐
│ Key │ Action │
├─────┼────────────────────────────────────────────────────────────┤ │ F6 │ Open configuration GUI (static/random mode, value sliders) │

Configuration

The mod's config file is located at:
.config/fakefps/fakefps.json

You can edit it manually or use the in-game GUI. Available options:

enabled (true/false) — Toggle the mod
mode ("static" / "random") — FPS mode
fakeFps (1-999) — Static FPS value
minFps / maxFps (1-999) — Random range bounds

Java Agent (Experimental)

An experimental Java Agent version is included for Lunar Client, Feather Client, and Badlion, allowing the same functionality on non-Fabric clients. Add
the agent JAR to your launcher's JVM arguments:

-javaagent:/path/to/fakefps-agent-1.0.0.jar

The agent uses bytecode transformation (ASM) to intercept the FPS method. It supports the same F6/F7 hotkeys and includes a Swing-based configuration
window. Note: the agent is experimental and requires ASM on the classpath at runtime.

Requirements

Minecraft 1.21.11 / 26.1 / 26.1.1 / 26.1.2 / 26.2
Fabric Loader >=0.19.3
