What it does

Calcium reworks the level renderer so the client skips work that does not change what the player sees, a method the author calls render skipping. The goal is a higher frame rate on the same hardware, and the author describes the gain as large in the mod text. The description is not backed by any measurement in the catalog data, so the exact amount is not stated here.

Only the client needs Calcium. A server does not have to run it, and players who join a server without the mod are unaffected. The mod is for Fabric, and its one published file targets 1.20.4. Calcium is released under the GNU Lesser General Public License v3.0 only and is open source, with its source code public.

Calcium was first published on 2024-04-01 and last updated on the same day. Snapshot builds are not part of its release.

Key features

  1. Render skipping

    The level renderer skips drawing work that has no visible effect, which the author calls render skipping.

  2. Frame rate focus

    The mod is aimed at raising frames per second, mainly for players who want the highest performance their machine can give.

  3. Client-only changes

    All changes happen in the client, so the server and other players keep their own setup unchanged.

  4. Light footprint

    The author describes the mod as lightweight, adding little overhead of its own to the game.
