if you want to use acedium with the newly released sodium 0.8.12-alpha.4 you can download an alpha version of acedium here (btw, this hasn't been thoroughly tested.)

Acedium Sodiumized

Acedium Sodiumized is an unofficial NeoForge 1.21.1 fork of Acedium, updated for Sodium 0.6.x.

It replaces Sodium's default terrain renderer with a specialized Nvidium-style NVIDIA renderer. This can improve performance at high render distances or in terrain-heavy scenes, but it may not help if terrain rendering is not your bottleneck.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.x
• Sodium 0.6.x
• NVIDIA GTX 1600 series or newer

Unsupported GPUs, including AMD, Intel, and older NVIDIA cards, cannot use the custom renderer. In that case, the mod should stay inactive and Sodium's normal renderer is used.

Limitations

• Iris shader packs disable the custom renderer. This is expected.
• Compatibility may be worse than standard Sodium because this mod replaces Sodium's terrain renderer and depends on less commonly used NVIDIA OpenGL extensions.
• Only NeoForge 1.21.1 is currently targeted.

Support

If something is broken, do not be afraid to open an issue on GitHub. I will try to reproduce it and fix it. You are also more than welcome to request new features or compatibility support.
