Iris is committed to ensuring mod compatibility as a first priority, and is already compatible with many of your favorite mods!
Iris has been built from the ground up to be extensible and easy to update. Say goodbye to weeks of waiting to use shaders on the new Minecraft version!
Iris is an open source mod that anyone can contribute to. This allows Iris to improve by facilitating collaboration.
Iris aims to have full support for all past and present OptiFine
shaderpacks, and number of packs supported by Iris is constantly
and rapidly growing!

Iris improves the way that Minecraft renders entities and
block entities like chests, pigs, and item frames. This trick
even works with shaders disabled, and in worlds with a lot of

percent. Shadow rendering sees an especially large
improvement, making areas that were once unplayable with
shaders into places where your FPS is surprisingly smooth!
