FPS Reducer 1.18.2 is a mod that decreases unessential GPU and CPU load by cutting down the frame rate. It happens if you’re not running Minecraft for a certain time.

After the user performs any operation, it will come back to the initial frame rate.
Features
- Lower FPS automatically under conditions below:
- No user operation for the specified period of time.
- The game window is not active or minimized.
- Suppress sound volume when Minecraft’s window is not working or minimized.
- Show the existing FPS on the screen edge.
- Display CPU usage of client thread (v1.14~)
Recommended in cases:
- When leaving the game operating without carrying out any task. For instance, with automated agriculture and/or industry.
- When doing other work and running MC in the background at once
- When you’d like to extend the lifespan of your PC even a bit
- When the room is hot…
How to use
- By default, if there is no operation within 5 minutes, the frame rate will be 10.
- Press PAUSE to bring down FPS by hand (new feature in 1.16)
- Hit END to open the configuration GUI by default
