Iris & Sodium lagging and less preformance

[Tenzorello]

What happened?

I decided to switch out Optifine for Iris & Sodium, but when I use my shaders it starts lagging. But on Optifine it works fine without any lag.

Screenshots

I used SEUS PTGI E12 to demonstrate the lag I'm experiencing with Iris & Sodium. This happens to other shaders but low-end shaders such as Sildur's Vibrant Shaders have less noticeable lag.
This problem does not happen in Optifine at all.
