It really shouldn't, since apparently (according to several youtubers/dataminers) Larian uses the "ceiling" of the map to preload a lot of assets not visible to the player.
This makes me sad. Not being able to look up kinda lets me feel like I'm playing in a shoe box. I guess I have to get used to it until release.
Me too. When I first started playing, trying to look straight ahead and not being able to almost felt like something was holding me down, like the back of my head had hit the ceiling of a very small room and I couldn't stand up straight. It was a bit claustrophobic. Over time I've gotten used to the angle and now it feels much more comfortable - fingers crossed that's the same for you.
