So I have been doing a lot of work on game optimization to deal with low FPS in mid to late game bases.
Low FPS Issue Guide
By Squall746
My recommendations to get your FPS back up are as follows:
Keep a tidy base, make sure there is no regolith or rare earths laying around. The game needs to track every one of them as an object.
Salvage old batteries and solar panels, less is more. Keeping your T1 solar panels and batteries can have a big impact. Same with T2 solar panels once you get T3
The RTG is not as useless as I thought. If you have enough of them, they have zero impact on FPS and produce power all the time. Replacing medium solar with RTGs will give you a FPS boost. When we get thermonuclear I dare say there will be a big boost to FPS as we can delete most of the solar and batteries.
Dont have too much over capacity. Having too many batteries even large ones comes with a penalty. When you get the later techs for battery optimization then you can remove some of the overcapacity. Same goes for when you have fuel generators or RTGs, you can remove excess battery capacity for a FPS boost.
Mid game you need a lot of modules to ramp up production. Late game you have the money so upgrade your modules and remove the extra ones that are no longer required. Less things for the game to track will give you a FPS boost. It’s almost like the 100% modules recycling tech is where it is in the tech tree for this exact reason. This also goes for CPU when you get the large CPU. Install them and delete old ones.
In my opinion having a lot of colonists to boost your production is better than having more modules. You can send them from production chain to production chain with the priority function.
Don’t have too much storage in your cargo dock. I try to keep mine around 100-150k and hold my cargo trucks off with the right ore composition to meet that target. I aim for 25% titanium, 20% silicone, 10% iron, 10% aluminum.
Something has changes in the game and there is far less slag. That said you should try and keep your slag to minimum if possible (more things for the game to track).
This one depends on your play style, but if you have storages on the surface for a FCC then a sushi belt for the high tech products might be enough. You don’t need each item to have its own belt and elevator. I only do this for the 4 basics and moving regolith, rare earths, and ice around
Try to keep your storages to a limit. I like to think of just in time production… with a buffer. Excess stuff in storage is more things for the game to track, I believe the demand goes down once its in storage but if its sitting on a belt and its moving then the game is tracking it (assumption not fact)
Keep your drone count to the minimum that you need while still being productive. Also the haulers seem to take a lot of FPS capacity. I turn them on and off only when I need them for a task.
This one is very specific to me, but my RAM was not operating at its full capacity. I had to go into my BIOS and enable XMP to go from 2133Mhz to 6000Mhz (DDR5). This had a big performance boost. I also over volted my CPU a bit. Make sure your windows power setting is set to high performance and not power saving. This is not technical advice and you should do a bit of googling before you change your settings.
This solutions took me from 9 FPS to a consistent 20 FPS and I completed the laser mission in good time. Good luck Crusties.
Also you dont need to use a lot of distributors. I find that bulk storages and large storages are better for dividing resources then distributors. You can also turn their outputs on and off as required. This will not drop the resources onto the ground and leave more things for the drones to track.
My factory achieved the laser mission ahead of time with the settings.
An idea of the factory layout.
I hope you found this helpful!
