Idle Tweaks
by Armandukx
With Idle Tweaks installed, Minecraft lowers its frame rate, render distance and sound while its window is unfocused or tabbed out.
What it does
When the game window loses focus, the mod caps the frame rate and restricts the render distance, so the client draws less while it sits in the background. A separate option mutes Minecraft's sounds during the same period. The mod is a client-side tool and does nothing on a server.
Idle Tweaks needs Fabric API on Fabric. On Forge and Quilt the page lists no required dependency, and IPCCraft, along with Quilted Fabric API or Quilt Standard Libraries, is listed as optional. Builds cover 1.8.9 – 1.21.11 across Fabric, Forge and Quilt, with 28 release versions. The mod is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source, though its source code, issue tracker and wiki are public.

Use cases
Leaving the game running
A player who keeps Minecraft open in a second window while working elsewhere can reduce the load the game puts on the machine.
Who it’s for: Players who leave Minecraft running in the background on a single-player or multiplayer client, and who want the game to use fewer resources while it is not focused.
