Gnetum

by decce6

Gnetum spreads each HUD redraw across several frames, so the game draws only part of the interface per frame.

What it does

The mod keeps two framebuffers. Each frame it renders one pass, a customizable slice of the full HUD, into the back framebuffer. Once every pass has finished, the back buffer is swapped with the front buffer, and each frame then draws the front buffer, which holds a texture of the complete HUD. With four passes, a full HUD update is spread over four frames, which saves many draw calls per frame and raises FPS.

Gnetum measures how long each HUD element takes to render and divides the updates accordingly, aiming to lift both average and minimum FPS. The idea is to refresh a HUD that is expensive to draw and changes rarely at a lower rate. Gnetum is open source under the GNU Lesser General Public License v3.0 only, is released for Fabric, Forge and NeoForge, and needs Fabric API on Fabric. Its files cover 1.12.2 – 26.3, with snapshot builds published alongside the release versions.

Key features

  1. Multi-frame HUD passes

    A full HUD update is divided into passes, and one pass is drawn in each frame.

  2. Automatic pass distribution

    Updates are assigned to passes based on the measured render time of each element.

  3. Adjustable pass count

    The number of passes sets how many frames a full HUD update spans.

  4. HUD FPS limiter

    A limiter sets the maximum frame rate at which the HUD is refreshed.

  5. Per-element caching

    Caching can be turned on or off for each HUD element from the Video Screen.

Questions

Does Gnetum need Fabric API?

Yes. Fabric API is listed as a required dependency, so it must be installed next to Gnetum on Fabric.

Does Gnetum have to be installed on a server?

No. Players add it to their own game, and a server needs no copy.

Does Gnetum work with OptiFine?

Yes, but OptiFine's Fast Render option must be disabled, because otherwise Gnetum has no effect.

Which game versions does Gnetum support?

Files exist for 1.12.2, 1.18.2, 1.20.1, 1.21.1, 1.21.4, 1.21.11, 26.1, 26.1.1, 26.1.2, 26.2 and 26.3.

What the author says

A Minecraft mod that improves performance by distributing HUD updates over multiple frames. Gnetum divides a full HUD update into multiple "passes." Only one pass is rendered each frame, reducing the time taken on HUD updates and improving FPS.
