- 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
