Anyone who is saying it doesn't render at whatever resolution is selected in the options is smoking something. I have been playing in 4k exclusively, and trust me, you can really tell if its 4k res or not. It has been for me, since the second the first version launched. Note that it straight up tells you that you need to restart for some graphical changes to take affect, so maybe they didn't restart?
What I don't see people talking about: the render resolution of objects in the inventory screen ( Like your multi tool ). This appears to be hardcoded to a lower resolution. I am certain it isn't rendering above 1080p on mine, but it even looks like it might be 720p. Not a huge deal I guess with all the other issues happening.
Honestly, I haven't had any crashes or anything with NMS PC. The only annoying thing I have encountered is the thing where if you are in fullscreen and switch out of the app for a moment, it has trouble coming back up on the screen without jumping through some hoops or restarting the game.
+1 for declaring this not a botched port, just a pretty bare bones one. Here is to hoping we get some more robust detail / distance sliders in the future.
