Dynamic FPS Mod (1.21.8, 1.20.1) – Intelligent FPS Optimization for Better Performance

Minecraft is known for its high resource usage even when it’s just running in the background. The Dynamic FPS Mod (1.21.8, 1.20.1) offers a smart, automated solution to this problem by optimizing game performance when the game window is inactive, minimized, or your device is on battery. With built-in frame rate management, volume adjustment, and system-aware detection, it significantly reduces CPU/GPU load without compromising gameplay experience when the game returns to focus. Whether you’re a laptop user or someone who multi-tasks often, this mod helps you save resources efficiently.

Features:

• Dynamic Frame Rate Adjustment
  Automatically drops the FPS to as low as 1 when Minecraft is unfocused, minimized, or hidden saving power when you’re not actively playing.
• Zero Rendering in Invisible States
  Completely halts visual rendering when the game window is fully hidden or covered by other apps, further improving system performance.
• Volume Control
  Gradually fades out or mutes in-game sound when the game is in the background or idle, creating a quieter environment while multitasking.
• Notification Management
  Pauses unnecessary in-game pop-ups and toast notifications when the game is inactive, preventing interruptions.

Battery-Saving Tools:

• Custom FPS Limits on Battery
  Set separate frame rate rules for when your device is running on battery, allowing you to conserve energy intelligently.
• Live Battery Status in HUD
  Displays battery charge percentage and charging/discharging status directly in-game.
• Battery Notifications
  Receive alerts when your battery level drops or changes significantly while Minecraft is running.

Smart Detection:

• Context-aware Game State Detection
  Dynamically responds to whether the game window is active, hovered, unfocused, minimized, or completely invisible.
• Idle Timer Configuration
  Customize how long Minecraft waits before transitioning into low-resource idle mode when no activity is detected.

Performance Fixes:

• Fixes excessive background CPU/GPU usage
  Addresses a common issue where Minecraft continues to render unnecessarily when minimized or unfocused.
• Stops rendering during loading overlays
  Prevents resource waste during splash screens, loading screens, or mod-loading transitions where visuals aren’t needed.

Why use Dynamic FPS Mod?

Dynamic FPS is a must-have for anyone who runs Minecraft in the background, plays on lower-end hardware, or uses a laptop.
