[Modded install] Strange stuttering, low RAM usage

[Stage]

Hello!

I hope it's alright to ask support for my modded installation.

1. I have noticed a strange behavior of Rimworld: I play this game on 2 different PCs (thank you steam cloud sync!). One is a desktop with an i5 2500k and 16GB ram, the other a laptop with an i7 4500u (dualcore ultrabook processor) and 8GB ram. Somehow the RAM usage of Rimworld on both machines is different. On my desktop my installation likes to take a steady amount of 1.5GB of RAM all the time, on my laptop however it varys between 1.5GB and 600MB. Once I hit 600MB on my laptop, the performance is abysmal. After restarting the game the RAM is back at 1.5GB and the game runs smooth.

2. I noticed a strange stuttering in later stages of the game. First I thought some mods are throwing errors, but according to log the only error there is is:

Couldn't relax research project coordinates apart after 200 passes.
Verse.Log:Error(String)
Verse.ResearchProjectDef:GenerateNonOverlappingCoordinates()
Verse.PlayDataLoader:DoPlayLoad()
Verse.PlayDataLoader:LoadAllPlayData(Boolean)
Verse.Root:<Start>m__735()
Verse.LongEventHandler:RunEventFromAnotherThread(Action)
Verse.LongEventHandler:<UpdateCurrentAsynchronousEvent>m__733()

I started several games to see if I find the issue, but the only thing I noticed was:
- too many animals
- the stuttering starts about 10 colonists. With lower than that, the performance is quite good.

Any idea where I should start looking?

Regards,
Stage

that research error is simply the research easing algorithm trying to move all researches apart so they arent touching any others, you have too many and have broken it, this is a known issue that hopefully will be address in the next release, it however doesnt impact performance.

What youve explained is strange but then A16 is full of memory issues it seems...

In relation to 1. What are the power management settings like on your laptop? As maybe your O/S is reducing the power usage on your system causing the performance and RAM usage to drop to conserve power (maybe).

There have been a few issues reported over the past few months that have been caused by some sort of power management interference (I assume most or all of these case are when the game is being played on a laptop). So if your laptop performance is noticeably worse than your desktop, then maybe the above applies to your issue as well (and if your laptop has a dedicated graphics card, then check the power management options on that as well).
