I'm playing on PS4 and starting to have some issues saving. I love this game, but it's about as buggy as I've heard in places. What did you all do when running into this sort of issue?
Are you on the latest version on PS4? I believe they released a patch just a few weeks ago that was supposed to have some performance improvements.
I played through earlier this year (i.e. before this latest patch) and noticed quite a few bug and performance issues. Some of the later game areas are particularly bad, tanking the frame rate down to sub-15 FPS on occasion.
The biggest issue I worried about was when navigating some areas or moving at high speed you need to be careful and let the terrain finish loading or there's a chance you may trap yourself out of bounds.
Save game wise, I noticed the further I got into the game the longer the saves would take, I don't think it ever took longer than a minute, but it's bad no matter how you look at it. I setup a chair in an observatory and made it a routine to sit in the chair and start the save process and just wait till the message saying the save finished before I'd move on.
I have seen some suggestions that saving gets worse the more objects you have in the world. That includes how big/many bases you build and how many items you leave lying around. I've seen the recommendation that you limit yourself to two bases of reasonable size and where possible avoid just dropping items on the seafloor if you don't need them. For anything organic you can generally put it into a bioreactor, for everything else you can put it in a trash can's inventory where it will be deleted a short time later.
