RT/PT-related shaders shadows grainy/shimmering/noisy

Any shaders that utilize any sort of Ray tracing or path tracing tech seem to have grainy/noisy shadows and distant block shimmering that are not present using Optifine. Currently affected shaders (that I have access to, cycled and tested through) include Rethinking Voxels, SEUS PTGI, Kappa, Nostalgia, Noble, Soft Voxels Lite. My hardware specs are Ryzen 7 5800X3D, RX7900XTX, 32GB 3600mhz RAM, 2TB Samsung 980 Pro SSD.

No This only happens on Iris and I tested on optifine as well, works fine there
