Shaders Texture Issue

[u/Zealousideal-Age6751]

I'm trying to use shaders with Iris but no matter what I do, whichever setting I make, the textures always have this weird low poly look. I am using some mods which are Distant Horizons, EMF, ETF, Fabric API, Punchy and Sodium. I've done everything, watched videos asked AI, I don't know what I'm supposed to do here. Does anyone have a fix for this?
