CharlesGrey: Next time try launching it directly, without Galaxy, just to see if the problem is related to the client. You can find the executable in the installation folder of the game. ( The Witcher 3 Wild Hunt\bin\x64\witcher3.exe -- Something like that. )
Could also be some other program causing conflicts, such as your Anti-Virus software.
sunshinecorp: Throw a blanket on him.
Also, try to post your game related problems in the
Witcher 3 sub-forum.
People using GOG main forum only to post Witcher related questions is getting tiresome.
This site isn't just about Witcher 3 you know. :P
CharlesGrey: You're right, I guess the Witcher 3 threads do distract a little from all the wonderful political discussions. :P
Those discussions wouldn't be so bad if everyone would just shut up and agree with me! :D
