Inactivity Fps Unlimiter
by Ghost
Inactivity Fps Unlimiter stops the game from lowering the frame rate when the window is minimized or the player is away from the keyboard.
What it does
When the game window is minimized or the player has been inactive, Minecraft normally drops its frame rate to save resources. This Fabric mod removes that reduction, so the frame rate stays at the level set in the game options while the window is idle. It is a client-side mod: only the player's game needs it, and a server does not.
The mod targets Minecraft 1.21.6 only, with a single Fabric build published 2025-06-30 as version 1.0. Inactivity Fps Unlimiter is not open source and is released under All rights reserved.
Key features
Idle frame rate kept
The reduced frame rate used while the game is minimized or idle is removed, so the configured limit stays in effect.
Background rendering
Frames keep rendering while the window is minimized, which can matter when a stream or recording runs in the background.
Frame rate limit respected
The frame rate cap set in the game options continues to apply while the player is away, with no separate idle setting to adjust.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.

This does not change anything visual/ui in the game, and leaves the minimized/afk settings without…
