Epitaph Optimizer

by Wraithyl

Epitaph Optimizer is a lightweight Fabric utility that sets a group of video options to performance-friendly values when Minecraft starts.

FabricClient-side onlyCC0 1.0 Universal1.21.11

What it does

On startup the mod applies a fixed set of video settings, the same ones a player would choose by hand in the Video Settings screen, so no manual setup is needed. The settings cover particles, entity shadows, smooth lighting (ambient occlusion), clouds, leaf rendering and biome blending. Each value can be changed through the mod's config file.

The mod is client-side only, so a server does not need it and players do not need to install anything on the server. It is built for Minecraft 1.21.11 and Fabric Loader 0.19.3, and its one published file covers 1.21.11. The mod works through mixins and does not alter game logic, networking or the rendering pipeline. The code is released under CC0 1.0 Universal, and the mod is not open source.

Key features

  1. Startup video settings

    Particles, entity shadows, smooth lighting, clouds, leaves and biome blend radius are set automatically when the game starts.

  2. Config file control

    A config file lets the player keep or change each applied option, since the mixins are configurable.

  3. Opaque leaves

    Leaves are drawn as fast opaque cutout blocks instead of see-through, which changes their look and render cost.

  4. Minimal particles and fast clouds

    Particles are reduced to a minimal setting and clouds use the fast renderer, without any change to gameplay.

AetherTune is client-side only, under the MIT License, for 1.21 – 1.21.11, and is not open source. Raised Clouds is open source under the MIT License, is client-side only, and covers 1.16.2 – 1.21.4, so it reaches older versions than this mod.

Questions

Does Epitaph Optimizer need Fabric API?

No required dependency is listed for Fabric. Installation needs only the mod on the client.

Do servers need Epitaph Optimizer?

No. Only the player's game needs it, and servers run without it.

Can the applied settings be changed?

Yes. The mixins are configurable through the config file, so each applied option can be kept or changed.
