About this Mod
Description
This mod reduces unnecessary GPU and CPU load by reducing the frame rate automatically when the client window is inactive or you are not operating the Minecraft for a certain period of time (optional from v2.0). As soon as the user performs any operation, it returns to the original frame rate.
Features
- Reduce FPS automatically under the following conditions.
- No user operation for the specified time.
- The game window is inactive or minimized.
- Suppress sound volume if the game window is inactive or minimized.
- Display the current FPS on the screen edge.

- Display CPU usage of client thread. (v1.14~)

Recommended in the following cases
- When leaving the game running without the operation, for example with automated agriculture and/or industry.
- When doing other work concurrently with running Minecraft in background.
- When you want to extend the lifespan of your PC even a little.
- When you want to save unnecessary power.
- When the room is hot...
Usage
By default, if there is no operation for 5 minutes the frame rate will drop to 10.
Pressing [PAUSE] key reduces FPS manually. (new feature in v1.16)
Pressing [END] key opens the configuration GUI by default.
Note
This is a client-side mod, so it is not necessary to install it on the server.

Does FPS Reducer need to be installed on the Minecraft server?
No. Modrinth marks FPS Reducer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does FPS Reducer require?
Use a file for fabric, forge, neoforge, quilt and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. Files for different loaders are not interchangeable.
FPS Reducer is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
