I'm skeptical if "full screen" or "windowed full screen" honour the resolution selection.
If I run it at 1920x1080 "fullscreen" or "windowed full screen", it is clearly just running at the native monitor resolution (3840x2160). The FPS drops to 15-25, (I have all the graphics sliders set to maximum) and when I took a screenshot it was 3840x2160. Turning on the "performance mode" gets the FPS into the 40s-50s.
If I run the game in a 1920x1080 window, it's showing high 50s to pegging the 60fps vsync cap. But it only takes up a quarter of the screen then, so it's unplayable.
I'm using a Ryzen 3900X with a GTX1080 with nVidia drivers v466.47. That should be sufficient hardware for all the eye candy at 1080p.
Another possibly confounding factor: I have a dual monitor setup (two 3840x2160 screens). Usually when I start a game on one screen that drops the resolution (working example: Guild Wars 2), there's a "jank" moment where icons or other windows get shunted around and tossed on the other screen. This doesn't happen with BnS, which seems another hint that it's not adjusting the resolution.
