In short, this mod is meant to reduce the impact on your computer (cpu/gpu) when you're idle, by reducing your FPS to a custom value (see screens).

This mod has no bloat and is as minimalistic/optimized as possible. It uses the vanilla field without modifying its structure, avoiding conflicts with other mods since it's doesnt use mixins to edit the field, which is also more lightweight.

It's meant to be compatible, lightweight, simple, straight-forward, and useful:) - I originally made this mod for my personal use. Keep in my mind that

⚠️This mod does not give you more fps in the game⚠️

Default message (configurable) when idle, reducing FPS to 15.

You can configure in the mod's configuration:

Default FPS: The fps set when you're not idle
Idle FPS: The fps set when you're idle
AFK timeout: After how many seconds you're considered as idle
Show Idle Msg: If you want to show the message (basically enable the mod)
Idle Message: What message you want it to be (%s for the amount of seconds)
Dark background: If you want a dark background behind the message
