I don't have this issue with any other game but my video seems to blank out during the game. Usually during fights, but also did it crafting once. The monitor is getting no signal, but I can still hear the audio in the background. No keys help or do anything. I have to turn off and on to get back. It's like the graphics card just stops working. I have a NVIDIA GeForce GTX 560Ti. It's a 64bit win8.1 OS. I didn't get this during beta. I set some of my graphics settings lower, so hoping that might avoid the issue. Don't really see much different from high to medium.
