Nothirium 1.8.9 port
Nothirium 1.8.9 port is a Forge mod for 1.8.9 that replaces Minecraft's chunk rendering engine with one that uses modern OpenGL.
What it does
The port brings the Nothirium chunk renderer to Minecraft 1.8.9 as a mixin-based mod. It changes how chunks are drawn on the client, and the author notes that it greatly increases performance. Because it runs on the client alone, servers do not need it, and players can join without installing anything. It requires RenderLib v1.4.5, which has also been ported. The mod is published for Forge only, with the latest file 1.8.9-0.4.9-beta-2 dated 2026-07-25, and it is released under All rights reserved, so it is not open source.
Key features
Modern OpenGL chunk rendering
Chunks are drawn through a rendering path built on modern OpenGL instead of the vanilla pipeline.
