Features for shader pack developers: Once Iris has full support for existing shader pipeline features and is reasonably bug free, I want to expand the horizons of what can be done with Minecraft shader packs via adding new features to the shader pipeline.Backwards compatibility: All existing ShadersMod / OptiFine shader packs must work on Iris, with no modifications required.Mod Compatibility: Iris should make every effort to be compatible with modded environments.

Accuracy: Iris should try to be as flawless as possible in its implementation.Performance: Iris should make full use of your graphics card when combined with optimization mods like Sodium.It is still in full development, receives new improvements very often, and progresses very fast! Iris Shaders goals Iris has a public stable release for Minecraft versions 1.16, 1.17, 1.18 and 1.19 / 1.20.

Iris, combined with Sodium, offers excellent performance on all computers, which finally allows you to play with the shaders instead of periodically activating them to make nice screenshots. The advantage of the Iris shader, is that it is compatible with Sodium, the best rendering optimization mod out there, by far.

OptiFine, the current dominant mod for loading shader packs, has a restrictive license that firmly prevents any sort of tinkering, and is quite notorious for having compatibility issues with some Minecraft mods. Iris was created to fill a gap detected by its creator: there was no open-source Minecraft shader that allowed loading shader packs on modern versions of the game, while maintaining performance and compatibility with modpacks. Iris is a new shader for Minecraft compatible with the Fabric API that promises exceptional performance…
