Lag/Stuttering caused by unidentified mod

[firestrock]

Hey there,

I'm about to start a new Rimworld playthrough and after spending alot of time searching for and filtering out mods I came up with quite the modlist. Everything is working fine(ish) and there are almost no errors on startup so I decided to give it a go.

My problem is that my game seems to stutter for half a second every ~9 seconds. The delay between the stuttering is always the same and seems to be affected by game speed. At x3 speed it happens every ~3 seconds so it seems to be linear.
I tried randomly deactivating mods but that only slightly increased the delay between the next lag but didn't completely remove it. When I removed all the mods the game was running fine.
The stuttering also occurs in the modlist (Mod Manager by Fluffy) roughly every 6 seconds, but not in the main menu or any other menus. There is nothing being printed in the log.

Before I spend a few days disabling every mod one-by-one I wanted to ask if anybody had the same problem and maybe can help me find the mods causing this.

If you don't get any help so far.
You should do the 50% methode.
Deactivate half of the mods (beside libaries and modmanager) with that methode you should find the bad mod faster then when you do it one by one.

[firestrock]

Thank you but that's how I found out that it only increases the delay and doesn't get rid of the problem completely. I'm afraid that it isn't caused by one mod alone but by many. That's why I'm estimating it will take days to debug.

[firestrock]

I think I got it. I noticed that every time the game lags the memory usage goes down. Maybe it has something to do with the garbage collector. In that case only user19990313 can help.

[jay124]

Was wondering if you ever managed to figure something out? I seem to be having the same issue, I noticed the frametime spikes to something like 300ms when the stutters occur.

Same thing as you, no stutter with vanilla. Though I start noticing it after enabling about 15 mods or so and any after that just makes them more frequent.

Did either of you ever figure this out?

I've been having this same problem since the 1.0 release last year.  I never could trace it down.  It becomes more obvious the more mods you add.  All I need to do to test it is start a new game and speed up time and watch a river freeze up briefly every X seconds.  It happens in vanilla too, and it doesn't take many mods for it to become much more noticeable.  Currently I've only got 13 mods enabled and it's super obvious.  Once there are 50+ mods, the stutter lasts longer and happens more often.  I reinstalled my OS entirely over the summer (finally upgraded from Win7 to Win10), so I'm pretty sure it's a game thing.

Since only a few people encounter these thing's even on plain vanila gameplay. I am pretty sure it isn't a game thing.
Or alot more people whould have these problems.

upgrade isn't a newinstall, i am pretty sure you keep most installed app's too.
It would interesting to know if you encounter the problem's on a fresh installed window's with nothing else installed too.
But that is something we can't await

It was a fresh install, not an upgrade.

I had this problem and it turned out to be Prison Labor. Not only did it glitch out and totally remove all my work box priorities but it also throws errors like crazy for me, probably due to some mod conflicts. Either way disabling it completely killed the stuttering for me, which makes sense since it's apparently still not a full release.

[Canute]

Scorpinax,
but they don't have error's and some of them say they have these lag's even without mods.

[Penchekrak]

I can clearly reproduce the issue just with HugsLib and Mod Manager. Probably, there is an issue in game itself. More mods you add, stronger lags you get. Will provide a video on request. Hope Ludeon Studios fix that asap (probably, not and that is sad).
IMO, most players plays with couple of mods or vanilla only, there are also lags but not as noticeble.

[Penchekrak]

Here is the video with timings: https://www.youtube.com/watch?v=sawWgNF5tmQ
There are four situations:
1 - Core, HugsLib, Mod Manager
2 - 10 mods
3 - 30-40 mods
4 - over 100 mods
All situations are without errors in logs. Lag spikes are clearly seen in all situations. Tested on Win7 and Win10.

I noticed RimWorld was loading things from mods i didn't have anymore, try to do a clean install: uninstall the game, delete the game folder AND the documents folder.
I'm testing right now and i had to spawn 80 colonists to start having freezes again, the lag spike from the gabage collector is like a frame skip, barely noticeable, with 3x speed and 4 mods: startup impact, mod manager, runtimegc and hugslib.

Try that out and let me know!
