Dynamic FPS

by juliand665

Dynamic FPS lowers frame rate, volume and other activity while the game window is unfocused, hidden, idle or running on battery.

What it does

The mod detects whether the window is active, hovered, unfocused or invisible. For each state, frame rate, volume and paused toast notifications can be set separately. The same settings apply after a custom idle timeout and when a laptop or handheld runs on battery, and battery status can be shown on the HUD with toasts about battery changes.

It also fixes a vanilla bug that causes higher background CPU usage than needed. Required on Fabric: Fabric API; optional: Cloth Config API and Mod Menu. Dynamic FPS needs no server copy, is open source under the MIT License and covers 43 release versions, 1.14.3 – 26.3.

Key features

  1. Window state detection

    Active, hovered, unfocused and invisible windows each get their own frame rate and volume.

  2. Idle mode

    After a set idle time the game drops to reduced settings until input returns.

  3. Battery mode

    Separate limits apply on battery power, with optional battery status on the HUD.

  4. Background CPU fix

    A vanilla bug that raises CPU use in the background is fixed.
