Performance issues at bigger colonies

[zenfur]

I face third time a problem when in bigger colonies (44 colonists atm) at some point game becomes unplayable because of freezes for 3-4 seconds every 2 seconds. It ruined my another great play. The game didn't gradually slow down, it just at some point started to behave like that. I wonder what could be the cause.
Running out of memory could be the reason, but I checked that it uses around 1.4 GB, while I have 8 GB available. It's possible that my OS (windows 7) doesn't allow it use as much memory as it wants, yet I don't know if that is the case.
Once I suspected path finding algorithm as once similar thing appeared when manhunter pack consisting of 100+ wargs had to find a way to my colonists around whole map, and it stopped when I closed the only gap for my colony.

I'd be happy if you could suggest something how I could improve game performance, as I cannot finish the game as it always becomes unplayable when its the most entertaining.

I'd note that while I use some mods (hardcore pack), but I did have this problem even with vanilla game.

Here is part of MSinfo32, if needed I can provide more.

Overall I hope rimworld will get some performance upgrade like prison architect did. Factorio while still in its alpha state doesn't have such issues even at extremely big maps.

Forgot to add, it's probably important. Usually it becomes after the game accumulates some minor bugs through gameplay, usually they don't interrupt and are only shown after game load. These are usually about multiple definitions of things in memory or missing objects/jobs. Once I had a situation when there was a reference to non existing thing and game was spewing out exceptions and thus was very slow, but I removed in save file this reference and it got fixed.

Also I suspect job giver, because now when while paused I draft/undraft everyone in my colony it takes ages and it was normal before this performance issue happened.

Everyone experiences that lag at some point... easy way is to get a better CPU  . I get it at around ~1000... oh well

[zenfur]

I have quite good CPU. I suspect we are not talking about the same thing. I am talking about bug, you are talking about lag.

I have done further research and I suspect job giver is the reason for that behaviour.

[Coenmcj]

Mmn, you're talking about the result, whereas Zenfur's talking about the cause.

[TheGentlmen]

Eh... sorry... I personally think its the pathfinder... not the job giver... why i say that you ask? Becuase if I have a ton of raider going to my base throu a hole in the wall, then I seal the wall it lags out to death (Thats after multiplying the size of raids by 50x). Job givers simple... Find posible job then give job of highest pirority. But then it goes "How do i get to the job" and starts to lag out.

[isistoy]

Would imagine some jobgivers and workgivers are using CanReserveAndReach and also trying to make consistent queries on memory db chunks...
More than guessing, profiling figures could help getting a better view of things!

[zenfur]

Pathfinder does generate the lag in bigger raids, yeah, but it's the separate cause. I am experiencing bug where colonists are doing nothing starting 10 jobs in 1 tick. I suspect that more.

Also the reason I excluded path finder is because one game was unplayable at some point, but I chose bigger map. This time I chose the smallest and situation is similar.

[skullywag]

its actually searching for jobs thats the cause, if you have no idle pawns the game will run fine, the moment you have idles the lag starts to build up, its way more intensive to search for a job than it is to do a job.

[zenfur]

I don't have idles, all of them are busy.

[skullywag]

Then as stated youve just hit that point where it lags even with no idles. The game is not optimised yet.

I have this exact same issue no matter what I do in my world and I know it has nothing to do with my hardware at all as rimworld is never taxing my CPU above 20%.
