My UPS hovers around 55 (sometimes even less) despite the game updating fast enough to allow for 60. This already occured about a month ago. I removed some of the more performance hungry mods but the issue still stands. Older images:

You're getting UPS drop because rendering is taking too long due to your video card. The game drops FPS first if it can and then when that drops too much it starts to drop UPS.
If you want to get ahold of me I'm almost always on Discord.
How does that explain the second and the last screenshot? It also doesn't explain this at all: My FPS drops down to 13 and I still get nearly 60 UPS.
Edit: I experimented a bit and the UPS seems to drop when I have less than 30 FPS. That still doesn't explain why I get around 55 UPS when I have 35 FPS.
Edit2: I dont think what you are saying is actually the cause of my problem:
