Aetherium NeoForge

Aetherium is a client-side performance and video settings mod. This project is the **NeoForge** build. It needs nothing else installed: no extra library or API mod.

It replaces the vanilla Video Settings screen with its own animated screen, and adds frame-rate features that work together with the vanilla renderer.

## Features

**Aetherium terrain renderer** (on by default)

– Skips the faces of each chunk section that point away from the camera, so the GPU draws less terrain.

– Never issues more draw calls than vanilla.

– If anything goes wrong, it switches back to vanilla rendering by itself instead of crashing.

**Performance**

– Entity occlusion culling: mobs and block entities hidden behind terrain are not drawn.

– Smart chunk culling: chunk sections fully inside the distance fog are not drawn or rebuilt.

– Smooth chunk loading, worker-thread sizing and a block-entity render distance.

– Even frame pacing with a max framerate set, for steadier frame times.

– Fast particles, visible-only animated textures and fast mob models (on the Minecraft versions that support them).

**Video settings screen**

– Animated, tabbed screen: General, Quality, Performance, Backend, Effects and Android.

– Light and dark theme, a draggable scrollbar, touch scrolling and interface sounds.

– Hover over any option to see what it does.

**Extras**

– Dynamic lights from held and dropped light sources.

– Zoom with smooth animation, scroll-to-zoom and rebindable Zoom / Zoom In / Zoom Out keys.

– Freelook, plus fog, sky and per-type particle controls.

## Compatibility

– **Minecraft:** 1.20.4, 1.20.6, 1.21 to 1.21.11, 26.1, 26.2 and 26.3. Download the file for your exact Minecraft version.

– **Loader:** NeoForge.

– **Client only:** not needed on servers. You can join any server with it.

– **Graphics:** targets OpenGL 3.0, so it also runs on older GPUs and on Android launchers.

– Versions 1.21.5 and newer are marked Beta because they have had less device testing.
