Terrible performance with scatterer, EVE, or parallax. What can I do?

[Drepface]

As the title says, I am having near unplayable performance with any of these mods. (30-15 fps on planet surface and slow-mo) My mission clock is solid yellow and about half to one third speed compared to normal, even with a 1 part rocket.
  -PC: MSI 2080 super, Ryzen 9 3900x, 64 GB ddr4, 1 TB m.2 ssd, 1440p monitor
I have tested my CPU on cinebench, since it seems to be the problem, but my cinebench results are only a couple percent slower than a couple tests I found on youtube. I have talked to Stratzenblitz about it, who has made a whole video on CPU performance (ryzen 9 3900x VS ryzen 9 5900x) with scatterer loaded up, and he got much better performance. I have talked to Linx, the parallax dev, and he gets 60 fps at 4k with a similar power intel cpu and a worse gpu (1080ti). I have talked to people with mid gen i5's and 1060 6GB's, who got 60 fps at 1440p. I have even talked to someone who was using integrated graphics who got better performance than me. I have tried turning my windows power options to highest performance. I have tried a fresh install. I have tried sending my computer to get fixed. Nothing has worked.
Is there anything I can do? Is it maybe a motherboard throttling issue? Did I miss some setting?
