Galaxy fires the larian launcher which in turn loads the game exe
Galaxy tracks your time in game, your screenshots, and your network so thats F12 to place a screenshot in folder X, 100 hours played and the fact that two of your pals are currently online if you want to multiplay
The larian launcher is in charge of running video & feedback scripts so if your system doesn't have the current Gpu driver that info is stored and in the game locks up it can send [with your permission] a error report back to Larian witch is far more helpful than most of the bug reports they actually get in this forum from people just saying this or that is busted... Tracking info still needs to be read by someone that understands code but its a clue
every single time you update the game the 'run as admin' needs to be reset... I personally do this at the Larian launcher and the main thing that goes wrong without that launcher running is the in game vids lock up
p.s, reports posted here are still helpful [mostly to other players] please say you run the game without this or that and if mods are included... if the 1st trader talk was a vid lock up then it could be because of the launcher but imo its much more likely a script error as patch 9 is riddled with these
