I have changed my hardware around DX update and had to reinstall the game therefore. It's hard to say whether it's due to one or the other change, but ever since then I cannot capture screenshots in-game anymore. I've heard some other players got the same issue as well. What could be the cause there? Perhaps permissions issue?
It doesn't work anymore since DX11 update. Instead of this as example, you can use Steam, Afterburner, Nvidia Shadowplay, AMD ReLive or print screen and paste it somewhere.
