The Raptr client has (for a month or two) not being tracking my gametime at all, I have it running but the overlay doesnt show up in any steam game (or origin) nor does it say I'm playing the game. It only works when I tell it to rescan with steam for the hours played. It also doesnt track Elite: Dangerous playtime.
I am having the same problem with DarkSiders 2. I know I have played that game for more than 4 hours, but it still says 2 hours.
