Before starting the game, make sure you set your desktop resolution to 4k. See this for other issues and fixes that should work with Beyond Two Souls as well.
I found the IGN Walkthrough! very helpful.
It tells you where to find everything.
Since I think, that your second time playing the game won't be the last I can only recommend that walkthrough a wish you a lot of fun playing it the second, third, forth, fifth,...time :)
