Smart FPS Booster

A client-side Minecraft performance utility mod that dynamically manages selected video and performance settings, provides real-time performance monitoring, and offers configurable optimization profiles.

Smart FPS Booster does not modify Minecraft’s engine and does not guarantee specific FPS increases. Performance results depend on hardware, installed mods, and game settings.

Why Smart FPS Booster?

Minecraft performance tuning often requires manual configuration and frequent adjustments depending on gameplay situations. Smart FPS Booster simplifies this process by:

• Applying predefined optimization profiles
• Dynamically adjusting supported client settings (optional)
• Displaying live performance data
• Integrating with popular optimization mods

The goal is to stabilize performance, reduce stuttering, and simplify configuration, especially on low-end or mid-range systems.

Intended For

• Players on low-end or mid-range PCs and laptops
• PvP players who prefer consistent frame timing
• Players experiencing FPS drops or stuttering
• Anyone who wants automated client-side performance management

Features

Optimization Profiles

Four configurable profiles are included:

• Max FPS – prioritizes performance-oriented settings
• Balanced – default mix of visuals and performance
• Quality – higher visual settings with moderate optimization
• Battery Saver – reduces GPU/CPU load for laptops

Profiles modify only supported client-side video and performance settings.

Live Performance Dashboard

Accessible via F8:

• Current FPS display
• FPS history graph (last 60 seconds)
• Memory usage indicator
• Session history (up to 10 sessions)
• Hardware tier estimation
• Built-in benchmark tool

Dynamic Optimization (Optional)

When enabled, the mod can adjust selected settings based on:

• Player movement
• Combat situations
• Heavy visual scenes (particles, explosions, large farms)
• Current dimension (Overworld / Nether / End)

All changes remain within normal Minecraft client configuration options.

Setting Locks

You may prevent the mod from changing specific settings:

• Render Distance
• Graphics Mode

This allows optimization while preserving your preferred visual configuration.

Lag Spike Indicator

Optional visual alert when a sudden FPS drop is detected (brief red screen flash).
This is informational only and does not affect gameplay mechanics.

Mod Compatibility

Smart FPS Booster detects and adapts behavior when used with:

• Sodium
• Lithium
• Iris Shaders
• Mod Menu

Compatibility is automatic when these mods are present.

Installation

1. Install Fabric Loader
2. Install Fabric API
3. Place the mod .jar into the mods folder
4. Launch the game

Important Notes

• Client-side only
• Safe to use on servers
• Does not bypass hardware limitations
• Does not guarantee FPS improvements
• Designed to assist configuration and performance monitoring
