UPS/FPS slows down to approx. 35 since update

[rldml]

Hello everyone,

because i'm unsure, i post it at this place. Perhaps i just doing something wrong.

Since the last update (1.1.57) i see heavy UPS/FPS-Drops from (nearly) constant 60 down to 35. this happens, when i'm zooming to max at the map. My CPU runs at 10% in that moment, none of its cores at max. Additionally the game uses only 3 to 4 GB of my RAM and my GPU has no heavy load at all.

Even when i'm not at the map and zooming in, i don't get back to 60 fps/ups. Strangely, i don't see any difference for my UPS/FPS when im turning the graphic settings to minimum. Turning all mods didn't seem to have any positive effect also.

Installed Mods: Better Lamp Contrast, Classic Mining Drill, Realistic Heat Glow, Science Pack Glow, Spidertron Inventory Sorter.
Removed Mods: Lamps on Map

My PC has a AMD Ryzen 9 3900X with 12 Cores, 64GB RAM and a Nvidia GTX 1080 wirh 8GB VRAM. Windows 11.

edit2: After some support through really nice discord-people it seems, my RAM is extremely slow. So i try updating this thing first.

Any hint is appreciated!
