Low performances - Unknown source

I really believe part of this issue is something to do with the way the game runs. I personally think that even though things aren't drawing in a visible area that it is still "drawing" them. You can see this by hitting alt + s to enable screenshot mode and zooming out all the way and seeing there isn't much difference in being zoomed in or way out on FPS.

 

I also personally hope the game's asteroids are broken up into smaller areas than just one giant area, but the way the dupe's path finding works it leads me to believe the game is a big area, mostly since the dupes tend to grab stuff near themselves rather than in an area near where a task is.

I tried it out on my system, and i'm not getting the FPS problems at all. It seems to run pretty much perfectly smoothly for me. My system's pretty much identical to yours (i7-8700, 1050 Ti) but with more RAM (32GB). I thought the RAM might be the thing, as my bases do routinely go up to and over 12GB, but this one was only using 8GB or so when i loaded it, so i'm not sure what the actual difference could be.

Edit: although i am running it on Linux... but i shouldn't think that would make such a significant difference.

I forgot to mention I'm on Windows 10, and my game is being limited to 4-5 GB of memory (while it still shows 12 GB committed).

It's definitely possible it's an OS related issue.

@Nedigo everyone is having same issues, there are LOTS and LOTS of posts regarding game performance. I have this problem too. Thanks for posting a bug.
@Nedigo @Yobbo check Task manager, the game is not hitting any limits, but still runs with low FPS. It's not the RAM issue. It's a game issue.
Here is a screenshot with a game running at 3x speed at 20-30 FPS, which means scrolling lags already. But no hardware limits are hit yet.



I've profiled the game a bit, it seems like it can't scale to use CPU properly and runs on 1-2 cores. When I've commented out in-game BrainScheduler which controls dupes and critters I guess, FPS went up by 15, looks like that's where most CPU is used.

It's been said over and over that a large chunk of frame time is spent on pathfinding, so it makes sense to find BrainScheduler being the culprit in your case. Also the game runs mostly on 1-2 threads so that adds up too.

But my issue seems to be different... For the simple reasons that deleting all dupes and most critters has no impact, and now that Yobbo mentioned that his system has no problems with my save file.

I'm down to removing the exact line you removed just to see if it helps, but I doubt it'll change at all for this issue.

@Nedigo I get 10-12 FPS at 3x speed on your save, 25 at 1x, again hardware is not used up.

I would like to point out the issue was NOT resolved in today's big performance optimization update.

I made sure to run the game a few days prior to the update and once again today, but there were no noticeable difference.

Still below 15 fps.
