FPS drops with no clear cause

[Hondamusprime]

Hello, I've been playing on a save for a few days now and I've started to notice that my game is experiencing sudden fps drops on different speeds with no reasonable cause. I've checked my GPU and CPU usage and there seems to be no issue there. I'm providing a screenshot of task manager when running.

I'm also wondering if there is a V-sync option anywhere. In most games I play V-sync lowers my average fps.

Rimworld isn't a 3D shooter or such kind even when it use Unity engine.
The bottleneck arn't the GPU
FPS drops/lags are mosttime based on database issues and/or errors that appear.
Enable the developer mode and check the error window if any errors appear.

When you got no errors you can't do much against the fps lag, beside not to play or larger maps/worlds and just 1 colony.
Maybe the next version get more optimized.
