Window Optimizer

Automatically reduces Minecraft's resource usage when the game window is minimized or loses focus.

Features

Smart Performance Scaling: Automatically detects when Minecraft window is minimized or loses focus
FPS Limiting: Reduces framerate to 1 FPS when window is inactive, saving CPU and GPU resources
Memory Optimization: Performs periodic garbage collection during extended minimization periods
Seamless Restoration: Instantly restores original performance when window regains focus
Background Friendly: Perfect for multitasking - lets other applications use system resources
Zero Configuration: Works out of the box with no setup required

How It Works

When you minimize Minecraft or switch to another application:

Framerate drops to 1 FPS
Render processes are optimized
Memory usage is reduced through smart garbage collection
System resources are freed for other applications

When you return to Minecraft:

Original framerate is instantly restored
Full performance returns immediately
No noticeable delay or lag
