What it does

On launch the mod calls the Java exit routine, so the game process ends right after it opens. The stated aim is to free the memory and processor time the game would take, which can help a computer with limited performance. The mod is aimed at the Optimization category and sits alongside the other tools in that group.

Key features

  1. Immediate shutdown

    The game closes as soon as it opens, using a call to the Java exit routine.

  2. Lightweight design

    The mod is small and has no gameplay content, so it adds almost nothing to the game it closes.

  3. Freed resources

    By ending the process at launch, the mod aims to release the memory and processing the game would use.

Questions

Does Mod That Closes The Game When It Opens need a loader?

Yes. Builds are published for Fabric, Forge, NeoForge, Legacy Fabric and Ornithe, and each loader needs its own file.

Does the server need the mod?

No. Either side can run it, and neither needs it, so installing it on one side is enough.
