Iris Shaders Mod For Minecraft 1.20.2, 1.20.1, 1.19.4
Iris 1.20.2-1.20.1 is one of the first Fabric shaders that work on a simplified and more advanced JSON programming language. In addition to more advanced features than JavaScript, this language is compatible with most optimizing modifications, which gives the player a beautiful picture and FPS boost at the same time.

As you know, Optifine HD is also moving towards the implementation of JSON, but sometimes it takes more time for the author to update his project simultaneously for both JS and JSON. To do this, there are separate optimizers or boosters that can be updated quickly and so you can improve vanilla graffiti almost immediately after updating the game.

In our case, we will consider Sodium, which is a very large project that has hundreds of features to independently update and optimize graphic elements and also work together with additional shaders.
Iris mainly focuses on Sodium, because shader scripts have “Class” parameters and can change dynamically (For example, microelements random in size and speed of movement). In front of the screen, the player can have thousands of such microelements and this loads both the processor and the video card very much. Sodium will be able to divide such elements into clusters and modules to create instead of one queue of thousands of elements – there will be hundreds of queues of only 10 elements, which makes drawing instantaneous and with minimal lags.

Shader Style

Iris uses the full potential of JSON classes, for example, it has become possible to draw new layers on top of others or to draw shadows in the background. This means that you will notice beautiful rainbows that have a completely new approach to realism. In addition, dynamic shadows have appeared, that is, the shadow from the sun will be as detailed and dark as possible, while from torches and other less bright light sources it is possible to get a blurred shadow. The author also used this feature for Ender World which will now surprise any player, just check it out. There you will see a huge number of 3D clouds and more different microparticles. It also has improved physics for water and an underwater camera effect that distorts visible light thereby creating reverse waves.
