Nothirium Mod 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. Full Incompatibilities: FarPlane2, LittleTiles, Albedo, Colored Lux. Partial Incompatibilities: Optifine: Make sure that ‘Smart Animations’ is disabled in the graphics settings. Also custom block render layer from Optifine won’t work with Nothirium. VanillaFix: Make sure that ‘textureFixes’ is disabled in the VanillaFix config. CensoredASM: Make sure that ‘onDemandAnimatedTextures‘ is disabled in the CensoredASM/LoliASM config.
