Good to know it isn't just my setup then.Yeah I have the same issue with the fullscreen mode, I think because the cut scenes and stuff aren't ultrawide compatible. Seems like just a poor implementation though and maybe it'll be patched down the road.
Performance is a bit iffy running Ultra though, even with my 2080 Ti. Like you, I'm not a fan of windowed mode since I feel there's always a performance loss.
I did get to ADA (reminds me of Portal) and board the ship, I'm not too certain on the dialog changing the story though, I died behind the ship (bunch of monster things there) a few times, so the save was on the ship. Both the options I picked when that lady confronts you ended up telling me to go speak to her boss in the town.
I'll agree the visuals are a bit hard to get into.
