I just got Witcher 3 and was so excited to play it, but I can't enjoy it. The game crashes every few minutes (around 5 minutes) without a warning. I'm playing it on highest graphics but as it runs smoothly I guess the graphics aren't the issue. One time it crashed when a cutscene came up, another time in the middle of a fight.
My OS is Windows 8.1, I hope you can help me to get the game running
EDIT: Downvotes, telling me the reason would be helpful, thanks
