[1.3.3287 - Vanilla] Game runs with low framerate no matter graphics settings

[Kromby]

Since about November of 2021, Rimworld has ran at ~10-20 fps no matter what save game I'm in.  So far I've uninstalled & unsubscribed from all mods, uninstalled/reinstalled the game, updated all drivers, tried previous versions, and verified the integrity of game files on Steam.  It doesn't seem like the framerate is hard capped as with using dev mode to remove the display of ground tiles, pawns, animals, etc. I can get up to 22 fps.

I'm not sure how to replicate this issue, so I'll list my system specs, a save file and my player log.  Hopefully this is enough to give some insight.

Specs:
1920x1080 & 1680x1050 monitors (tested on both)
GeForce GTX 1070 graphics card - Latest drivers & works fine for other games
AMD Ryzen 5 3600 - CPU
32 GB RAM
64 Bit Windows 10

The player log is attached to this post and the save file is on google drive at this link:

I hope there's a way to fix this, Rimworld is one of my favorite games and have been enjoying it for years.

EDIT:
Last night on 3/10/22, there was a ~12 MB update to Rimworld that wasn't listed on steam.  Not sure what that was, but now it runs smooth as butter!  I'm sorry if other people are having this issue, because I don't know how it was fixed.
