Potzato: If you haven't internet on your pc, you can't be logged in galaxy ? And don't tell me "I can launch the game so I have to be logged in" ;-)
ZFR: But shouldn't the time be tracked even when you play on Galaxy without internet connection?
As far as I remember, when you boot up galaxy there are big blue 'log in now' buttons. I am not sure you can
launch games through galaxy without being connected to your account.
What I know is if you play a game without galaxy being launched, it won't record any game time (and I even think it does have to be launched though galaxy to record progress)
As far as I understand OP : he's on the web with his phone (i.e. he doesn't use his phone as a bridge to get the web on his rig), his rig is offline, he launched galaxy on his rig, he is not connected, his galaxy client doesn't record anything.
