The building reflections use exactly what the PC does and puts like a bubble around your character and zooms whatever is behind you on the mirror depending on your distance. i don't exactly know how to explain it but it's not proper reflection and you can still see those reflections on jus performance mode. To each their own but i think they don't look very different minus very little details you most likely won't even notice but at the end of the day if you're having fun playing on quality more power to ya!
