GeckolibBetterFPS

by MoePus

GeckolibBetterFPS targets the rendering cost of GeckoLib animated entities, so frames stay steadier when many of them are on screen.

What it does

Rendering of GeckoLib animated entities is sped up by about 25 percent, according to the author. The mod works on the rendering pipeline, where GeckoLib animations are drawn, and cuts CPU overhead by removing redundant calculations and simplifying code paths that run every frame. Its focus is mathematical logic inside the rendering process rather than the animation content itself.

The stated goal is smoother play in areas with many animated mobs, with fewer micro stutters when several GeckoLib entities are present. The mod does not change how animations look; the author describes it as a change to performance only. It requires Embeddium and GeckoLib, and ImmediatelyFast is optional. Embeddium is the Sodium-based rendering layer for Forge and NeoForge that this mod builds on.

The mod is client-side only, so servers run without it and players alone install it. Files are published for Forge and NeoForge across two release versions, 1.20.1 and 1.21.1, under the GNU Lesser General Public License v3.0 or later, and the project is open source with public source code.

Key features

  1. Faster GeckoLib rendering

    Animated entities drawn by GeckoLib are rendered about 25 percent faster, according to the author.

  2. Fewer micro stutters

    Frame drops are reduced when several GeckoLib entities are present in the same view.

  3. Reduced redundant calculations

    Frequently executed rendering code paths are simplified and repeated calculations are removed to lower CPU cost.

  4. Animation output unchanged

    The mod targets performance in the rendering process and does not alter animation quality or visuals.

Use cases

Crowded animated scenes

Areas with many GeckoLib mobs on screen at once are where the author expects the largest gain in frame rate.

Who it’s for: Players who run mods that use GeckoLib animated entities on the client and notice frame drops when many of them are visible. It is not needed on servers or in worlds without GeckoLib content.

Questions

Does GeckolibBetterFPS need Embeddium?

Yes. Embeddium and GeckoLib are both required. ImmediatelyFast is optional and can be installed alongside them.

Does it have to be installed on servers?

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

Which versions are supported?

Files exist for 1.20.1 and 1.21.1, with Forge and NeoForge builds. The latest Forge file is 1.0.2 for 1.20.1 and the latest NeoForge file is 1.0.2 for 1.21.1.
