No, the resolution is legitimate. It might be that the amount of assets loaded is too much.
After leaving that comment I actually tried reducing the resolution in Windows and then loading the game, so it ran at 720p. It made a bit of difference but not too much.
Yeah erm, anything you can do to make the game a bit smoother on low spec hardware would be awesome :)
It's hard for me to comment on all of the game yet as I watched some on the Alpha Beta Gamer channel on youtube and then realised I didn't want to watch the rest as I wanted to play it myself!
From what I've seen though I agree with people that it's very atmospheric and also feels very real. And creates this feeling of being alone even within a busy city, which is powerful I think.
