I just downloaded the dx11 pack and now my display has a black border around it. I run the game 1920X1080....and this was not an issue when I had the basic 1.9 patch. It only started after I applied the DX11? Not sure if anyone has had this issue but I can't figure it out. I even do the alt+enter to try and fix it but it just gives me windowed mode.
