What it does

The mod runs on client and server, so both sides need it. Its main claim in the author text is better performance while it is active, though the Modrinth page does not describe the mechanism behind that claim. Files are published for Forge and ModLoader, both for 1.3.1 and both dated 2026-03-13.

The project is released under the MIT License and is not open source. The author is Tomanex, who is listed as lead developer, and the mod sits in the Optimization category with Game mechanics and Utility as secondary categories. Ten other Optimization mods have Forge files for 1.3.1.

Key features

  1. Performance-focused profiling

    The mod is built to make the game's profiling work lighter while it is active, according to the author notes.

  2. Profiler controls

    The mod is intended to keep its profiling overhead low, so it can run while the game is played.

  3. Lead developer credit

    Tomanex is listed as lead developer, the person responsible for the project's direction.
