Randonly while i playing the game simply close, without message error and nothing, just close. I passed for this with The Witcher 2 but i solved. And i suffering in TW3 too. But on the internet had no solve to this problem. Its just i passing for this? Can anyone send some tip to solve?
Thanks b0ss.

I have a Rx470, the problem still since i have buy the rx. So i dont think is drivers.

When a game or other program just closes with no indication or error of any kind, it's a safe bet that it's some background process interfering with proper execution, and the most likely culprits are security suites such as antivirus, firewall, or even some Windows feature (Defender?). Check all of your background processes and close or disable any that are not absolutely essential.
