I recently got a new RX 560, and to my surprise, some games don't go fullscreen. In fortnite, for example, it did work for the game to go fullscreen but the resolution was wonky and it became unplayable. In CS:GO I can't even start the game because I would always get the "Failed to create D3D device!" error. Same goes for Team Fortress 2, wich does start, but all I see is a grey screen and the a little fragment of the top left screen where it shows the name of the program that's running. I used DDU to uninstall all of my drivers before installing my gpu's new drivers off the AMD site. If anyone has an idea to what's happening, please let me know.
