Seaborgium

by UndefinedBHVR

Seaborgium is a client-side rendering optimization for the heads-up display, aimed at cutting frame-time cost in busy HUD scenes.

FabricForgeQuiltClient-side onlyISC LicenseOpen source1.18.2 – 1.19.4

What it does

Seaborgium targets the way Minecraft draws the HUD. Its uniform-location cache stores the result of the first glGetUniformLocation call for each requested uniform, and later lookups return the cached value instead of calling the driver again. Because the heart row is costly to draw when it holds many hearts, the cache matters most when absorption pushes the count to 255.

The mod ships as one unified jar that works on Fabric, Forge and Quilt, and it is published for 1.18.2 and 1.19.4. Since it runs only on the client, servers and other players need nothing. Its license is the ISC License, and the source code and issue tracker are public. Changes to the graphics backend, such as the Vulkan Mod, are known to conflict with it, so those combinations are reported to the issue page.

Key features

  1. Cached uniform lookups

    The first glGetUniformLocation result for each uniform is stored and reused on later requests.

  2. Heart rendering

    The HUD heart row is the main target, since drawing many hearts is expensive in vanilla.

  3. Measured gains

    With 255 absorption, the author reports average frame rates rising from 53 to 163, and gains of 30 to 50 FPS in regular play.

  4. Backend conflicts

    Mods that replace the graphics API, such as the Vulkan Mod, have known incompatibilities with it.

Questions

No. It is installed on the player's side alone, so servers need nothing.

Which loaders does Seaborgium support?

Fabric, Forge and Quilt. One unified jar covers all three.

Which game versions have files?

Files exist for 1.18.2 and 1.19.4, with 0.1.3 as the latest file for 1.19.4.

Is Seaborgium compatible with the Vulkan Mod?

Not reliably. Mods that change the graphics backend have known incompatibilities with Seaborgium.

What the author says

I am henceforth archiving the mod on github, and re-establishing it as public for on modrinth for archival purposes. Seaborgium provides a unified jar, which means it contains both the Fabric-like and Forge versions of the mod.
