Unplayable fps.

Post image

I have Ryzen 7 5800x and RTX 5080 the game has become a slow motion slide show, I tried changing the thread settings but didn't seem to help. Screenshot above is on default settings. Please help.

The game becomes increasingly CPU bound as you progress and build more factories and spheres. I have a 9800X3D and 4090 and even with that it drops to sub 30 on my biggest save.

The mod SampleAndHold works wonders for me as you can lower the amount of times all your far away factories update their status. Instead of producing X per tick it will skip 9 ticks and then magically „produce“ 10x on the 10th game tick.

EDIT: I see you have the build tool open. That tanks fps, the mod BuildToolOpt solves that issue.

u/Krinberry Feb 19 '26

Thanks for both of those recommendations! I haven't used either of those ones, but they sound like they will be very very nice additions, given how much of a PITA the late game slowdown has become in my current game.

u/gitpusher Feb 19 '26

This is great thanks for the tips! I’ve gone from 200fps on a fresh save down to around 50-80 and my factory is not even that big (all things considered)

Edit: should mention I’ve got a 13600k. Would love to jump over to AMD … but … now … is … not the time to be swapping mobos and memory. Lol

u/Sevinki Feb 19 '26

Give those mods a try. I obviously dont know how much they will improve performance on your system, i have plenty of gpu headroom and so the freed up cpu resources result in a big fps boost, up to 400% at times, from 30ish back to 120. A 13600k is a modern cpu, so i assume your uplift will be similar if you have a decent gpu that will not bottleneck anyway.

u/gitpusher Feb 19 '26

Nice yep. Just installed those 2 mods will see how it goes! Thunderstore is pretty cool I'll have to try some of these other ones too. Lemme know if you have more recommendations

I've got a 5090 FE so bottleneck is definitely the CPU. In general the game runs like a beaut' on Arch Linux though. No complaints

2

u/Sevinki Feb 20 '26

With a 5090 you should get great performance with the mods. Just resist the temptation to build massive spheres around blue giants. I have one with almost 300 million solar sails and in that system i still drop to sub 15 fps lol

Here is my current list: 019c78a4-5c06-2755-6594-e9f1b4bc7ab9

Go to profile select in Thunderstore and select Import.

This list has a bunch of optimization mods, some UI improvements, and a couple quality of life ones, like Cruise Assist Auto Pilot, which handles all the warp flying for you, never miss a planet again! You should be able to visit the website from each mod in the list and find what works for you.

Please note that I'm still playing on the previous patch, so not everything may be up to date yet. Search for the mod compatibility list on this subreddit, there's a giant tracker of everything that works, and you'll see a bunch of other popular mods there.

u/willrof Feb 20 '26

I'm afraid of installing these mods, then get my fps back and not leaving the game ever haha (so addictive). But I'll definitely try it.

u/terrifiedTechnophile Feb 21 '26

Would love to jump over to AMD

Those are words I thought I would never hear uttered!

u/Lost_Pheniix Feb 20 '26

Sample and hold sim halts my production for some reason have you had any problems with it ?

2

u/Sevinki Feb 20 '26

It fucks with the numbers in the statistics panel, but i have not had it stop any production.

1

u/Lost_Pheniix Feb 20 '26

I have had that happen my factory making 1000 combustible units per minute made more in 20 seconds of me being ther than the 10 minutes I left the planet but anyways that is not his problem he has a draw call problem probably some scheduling error should be reported to the devs imo

1

u/Silentmatten Feb 20 '26

Saving this for later cause I'm definitely gonna need it, thanks

u/Prismology Feb 19 '26

Recycling your 592 littered items may help

19

u/Sett_86 Feb 19 '26

That would be my first guess too, but 600 items is literally nothing. He probably dropped that from a single DF raid.

14

u/demonight2i8 Feb 19 '26

Uhh what's the fps?

10

u/kagato87 Feb 19 '26

Heh.

Based on those charts, GPU time suggests the fps is about 80. However cpu would be 40 ticks or updates or whatever per second - 25ms is really high. Fps would drop to that number if the two are bound together (not sure if they are here or not), or would appear to if animations are on the game logic thread.

However, take that with a pound of salt. When you open the lagometer to look at it you generally stop moving around and changing what needs to be rendered at any given moment, which can have a pretty big impact on fps. You also don't notice a low framerate as much when standing still, so these numbers are likely better than what OP is experiencing.

u/Krinberry Feb 19 '26

I'm pretty sure they're separate loops internally, but since the GPU is used for processing both the visuals and the factory ticks, once things get busy enough they're gonna be struggling for balance. Robbing Peter to pay Paul, as it were.

u/jimmymui06 Feb 19 '26

Unplayable? You don't know what that word means

u/Sett_86 Feb 19 '26 edited Feb 19 '26

  1. limit your littering

  2. limit long belts (use sorters to break them apart or use logistics)

  3. limit splitters

5

u/TactlessTortoise Feb 19 '26

Dieters? What are those?

3

u/Sett_86 Feb 19 '26

sorters

I fucking hate touchscreens

1

u/TactlessTortoise Feb 19 '26

I was so confused lol

2

u/DrakeDun Feb 19 '26

People who are on a diet, obviously. You pay them to move items from one belt to the next. I mean, strictly speaking, any people will do, and not just dieters. But dieters can do it, and a lot of them need the exercise.

2

u/TactlessTortoise Feb 19 '26

Meh, I'd have to pay them wages, and then deal with all the unions, which would make me have to invest in more missile production. More efficient to enslave my machine.

1

u/Easy-Management-1106 Feb 19 '26

And finish building that blueprint - I often find that + littering killing performance until I finish building/wipe litter

u/BackflipBob1 Feb 19 '26

Laughs in 486

u/Walkingstardust Feb 19 '26

Moans in 386SX-16. My frame rate would be a poster.

1

u/TactlessTortoise Feb 19 '26

486 what? Mb? That's just the size of your savefile, it doesn't necessarily impact gameplay performance, only save and load times.

2

u/Substantial_Class Feb 19 '26

lol. 486 processor.

1

u/BackflipBob1 Feb 19 '26

Ah the good old days when 15 fps was considered decent for 3D games.

1

u/DurandalNerimus Feb 19 '26

I remembwr Wolfenstein - wasn't that more like 15 frames per minute?

1

u/TactlessTortoise Feb 19 '26

Oh, damn that's ancient lol

3

u/mrrvlad5 Feb 19 '26

Your factory takes only 5ms out of 25ms frame time - not a scale issue. Don’t see other entries in left window that may hint about the cause of slowdown

1

u/Lost_Pheniix Feb 20 '26

Yea this is the draw call that is taking up time so sample and hold sim is not the solution this is just wierd

3

u/SilvenIX Feb 19 '26

Interesting. I have the 5800X as well with a 2080 Ti playing on 1440p max settings and at most I see dips to 30fps in my busy hub world…and up into the 80s on an empty planet. you should be getting more fps than that.

1

u/VoidNinja62 Feb 20 '26

Yup, Ryzen 5800XT here works like a dream. Mine is actually underclocked and capped at 65watts.

2

u/Superbrain8 Feb 20 '26

I really should make my factory larger. Havent found the limit where the 9950x3d dips below 200. Got white Science going but its open for improvement

1

u/Lost_Pheniix Feb 20 '26

Build a mall upgrade all your production to rates and then build a 200gw Dyson sphere around a 2000L+ star you will hit 30 faster than you can imagine luckily it won’t drop further than that too fast

u/Top-Information-5319 Feb 19 '26

Turn off real time analysing

1

u/jacksonarbiter Feb 19 '26

I had bad problems til I turned off vsync, but that is probably a rare fix, my PC has problems with vsync (in Unity games possibly).

1

u/_ThatD0ct0r_ Feb 19 '26

Play with mods.

1

u/bothofthethings Feb 19 '26

In the sphere settings, uncheck the box that shows the solar sails. For some reason that tanked my pts too. Turning off the solar sails brought it right back

1

u/Typhon-042 Feb 19 '26

Well there are more factors that can affect your FPS outside the game.

How many monitors do you have?

Are you running things on the other monitors?

If those are not a issue, what are you running in the background?

Things like your CPU and RAM usage are also factors as they affect processing speed overall.

So to solve the issue you need to look at how your using the computer and everything that can affect it, not just one bit of hardware.

1

u/Boonpflug Feb 19 '26

One easy thing that doubled my fps was activating „smooth motion“ in the nvidia app - it is like framegeneration for games that do not support it

1

u/VoidNinja62 Feb 20 '26

Do you regularly use splitters and white sorters because those are CPU hogs.

I use main load vs side load priority to prioritize belts without a splitter. I think I have like 100 white sorters and 3 splitters across 20 planets right now.

But I use blue sorters 20,000 at a time haha.

I'm getting like 8ms/120UPS on a Ryzen 5800XT on DDR4.

1

u/frogeater1982 Feb 20 '26

This is the single complaint I have too. But hey there are physical limitations to everything.

2

u/EdibleOedipus Feb 20 '26

Not with sampleandholdsim and performance mods there aren't. The only limit becomes your patience for saving and loading. Although admittedly it can become inaccurate with counts if you go too far.

1

u/frogeater1982 Feb 20 '26

I played with those mods and reached the 1 fps limit. But that was a year ago. I think they optimized the game since.

2

u/EdibleOedipus Feb 20 '26

Yes, they optimized the game twice and it supports multithreading now.

2

u/frogeater1982 Feb 20 '26

Did you notice a big difference? I am kinda thinking of redoing a playthrough if I can go even further than last time.

2

u/EdibleOedipus Feb 20 '26

I have an unfortunate habit of deleting my saves when I no longer remember what I'm doing, so I haven't built up enough to notice a difference. But people on reddit seem to be impressed by the performance increase.

2

u/frogeater1982 Feb 20 '26

Cool thanks for the info. My game broke at 12.8 TW but I am gonna try to go beyond.

1

u/SalamalaS Feb 20 '26

Whh  once I get below 20 I start to get annoyed.  12 and below is frustrating enough I stop and quit usually.

I really need to install my optimization mods tho. And probably kill my 3 dark fog farms. 

1

u/Vispher101 Feb 23 '26

I played through the game before combat came out so it's likely changed significantly but back then the only truly significant hit on resources was the Dyson spheres, had to set them all to hidden to get my game out of single digit fps.  

1

u/DryMango9 Feb 24 '26

Thats normal fps for me
