About this project
What does Nothirium add?
This mod requires MixinBootstrap (curseforge, modrinth) to run!
Mixin 0.7-0.8 Compatibility (curseforge, modrinth) might be helpful when another mod uses an older mixin version and you are thus unable to launch the game.
Nothirium is a client-side only mod that changes Minecraft's chunk rendering engine to use modern OpenGL which greatly increases performance. This mod is similar to Sodium but this is not a port of Sodium.
