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
Benefits
Better Multitasking: Work with other applications while Minecraft runs in background Reduced Power Consumption: Lower CPU/GPU usage saves battery life on laptops Cooler System: Less heat generation when game is minimized Smoother Experience: Other applications run better when Minecraft isn't consuming resources
Compatibility
Client-Side Only: No server installation required Minecraft Version: 1.16.5 Mod Loader: Minecraft Forge Performance Impact: Minimal when active, significant savings when minimized
