Iris mod gives outstanding performance with Shader and the reason for that is because it spills of over sodium mod and if you don’t know this mod it’s the ultimate OptiFine because it multiplies your FPS by a lot.
Another significant feature of the Iris Shaders mod is the addition of shadows. Shadows are cast realistically, depending on the position of the light source and the objects in the game world. This creates a more realistic and immersive environment, making it feel as if the game world is truly alive.
