FPS Issues when using shaders

I pre-generated a large distance around me so it shouldn't be anything related to chunk generation in theory. I get decent FPS when not using shaders but it plumets when using shaders. I thought at first that my GPU was just getting fully used since I was using shaders, but then I realized that it was sitting at roughly 25% usage while the CPU was completely pinned at 100% even with pregened chunks which I thought was odd. It could be normal behavior and my CPU could just be too weak, please let me know if that's the case. In case the photos are blurry, the shaders give me around 25 fps and without them I get about 140 fps. I included my current mods list but this also happens with just Iris, Sodium, and DH 2 installed. Specs: i9 9900KF @ 4.9 GHZ 32GB DDR4 3600 MHZ Radeon RX 6950 XT
