If you enjoyed Satisfactory you might also want to try out Dyson Sphere Program. It doesn't provide the veritical building but it is a different take on the factorio/satisfactory style of gameplay.
I tried DSP, very fun game but the performance is terrible. i7-9700K and RTX2080 and I get 20 FPS before using even 1/10th of the first planet. Can't recommend it currently.
I've only played the demo of factorio, but on the same computer (AMD Ryzen 5, RX540) DSP runs much better for me - there's a noticeable slowdown on save now that I've covered about half my starting planet but other than that it's stutter free.
Interesting, while i haven't built a sphere yet I have factories going on multiple planets and haven't noticed any performance issues. I'm on a a 2700k with a 970GTX. Not suggesting you don't have issues, but perhaps there is a fix?
Satisfactory is freakin incredible and it is easily the best new game I have played in the last 10 years.
