Insane stuttering on high end pc

I have a 4090, 7950x3d cpu and 32gb of ram. I have seen videos of people showcasing this mod so I decided to install it with bliss, sodium, iris, indium, C2ME, Noisium, Tectonic and Terralith as the videos show and I allocated 8gb of ram.

When I play, everything begins to stutter and I cannot move or look anywhere without stuttering. Anything higher than 128 LOD with minimal impact cpu load and distant generation set to false causes stutters. I feel like something is wrong because my computer is very powerful and has similar specs to the YouTubers who show off these mods with seemingly no issues.
