I think mods could fix the interior issues, add some variety instead of using the same science outpost interior for every science outpost. They did a great job with those interiors, but ya.. after I've explored one or two I know where most things are and its.. not very fun.
Finding all the flora/fauna is really terrible right now. I'd expect ~30 mins tops per planet to find everything, but it seems like it takes multiple landings sometimes and nobody has time for that; nor is it "fun".
I have it running "mostly" stable on my i5, I had to use the 512k low res "Starfield Performance Texture Pack" (https://www.nexusmods.com/starfield/mods/510?tab=description) but still get the occasional crash but often hours of play before that.
