Insect attack FPS drop to 1

[Osa]

I know the game has problems with FPS and I've always found a way to cope somehow, but I'm at a point where I can't continue playing because I'm being attacked by insects and the FPS drops to 1.

However, the biggest incomprehension I have is because the game doesn't use the PC resources at its disposal. The FPS drops to 1, but the CPU utilization is at 30%, the GPU utilization is at 20%, and even the SSD is running normally, so I can't see anywhere in the system why the game isn't drawing power.

I tried changing process priority, turned off fullscreen optimization in Windows, ran it as admin, tested -popupwindow, tried triple buffer in Nvidia, latency, thread optimization, Vsync settings, FPS settings, exclude process in antivirus, graphics performance settings in Windows on High Performance, tried mods.... none of it had any effect on the FPS issues in RimWorld.

I just wonder what is wrong with RimWorld. Normally a running game likes to use up to 100% CPU and or GPU, but not here. You'd think that if the FPS isn't working and there are performance issues, the game would need more resources. It seems like there is a brake on somewhere.

I've never had an FPS drop. It's your PC or settings or you're using mods or you've set the map to the largest it gets or all of the above.

The game doesn't have FPS issues. It can have TPS slowdown on very large/long or heavily modded games, but TPS is very different from FPS. If you are having the game drop to a slideshow like 1 FPS then something is very wrong with what you are doing as Raelic suggested. My guess is mods.

As far as how much of your PC the game is using, very few games use 100% of both CPU and GPU, in fact these days people would cry and whine about that like it's breaking their system because they are oblivious to how their hardware is supposed to work. Most games are heavily bottlenecked one way or another, usually in a CPU thread for complex games or in the GPU for overly visual games. It takes a perfectly balanced game mechanically with perfect optimization to run at 100% CPU and GPU at the same time.

RimWorld has essentially no need for the GPU, the game has very basic visuals which is why it's easy to maintain solid FPS. The main simulation thread is as that sounds just one thread, it can only run on one CPU core and most of the other threads have to wait to some extent for that simulation thread. So if the game is overloaded the simulation speed slows down (the TPS), but the UI, sound, video, etc. threads all keep running fine. This generally means you have one core of your CPU running at 100% and the others don't have much to do.

None of my CPU cores have a high utilization.

When I look at Dubs Performance Analyzer I find the following:

Can anyone pls tell me what the problem is? It shows me that it is core game, but I do not really know the tool.

Try rimthreaded and see if problem persists. Rimthreaded allows multithreading:

Otherwise it obviously is a bug.

Activate Dev mode:
Open console and clear it, spawn a insect and have it attack. Since this has to be some mod bug/ issue, it will probaly spamm unlimited errors, probaly about "missing injury......./body part......illegal operation...." something about those line maiby as of my experience.

Copy those errors and upload them using the given upload tool, copy the line and use that. it will help you more then guessing games.

RimThreaded had no effect on my problem, I also tried other things, for example if I remove all animals, including the insects of the raid in developer mode I get about 20 FPS again. That's good, but not the reason for my problem.

Then I went through mod after mod until I found the problem, it's the mod Avoid Friendly Fire, after I disabled the mod the game immediately ran at 60 FPS again. Have passed it on to the developer of the mod.
