I am able to run directx 11 mode of the game, but it's in windows mode. I changed my graphicsettingsdirectx11.ini file to fit my screens resolution. It's still in windows mode, it's playable. However, there is another problem. I can't choose any of the option from a dropdown selections window, such as setting the adviser level and all of the graphical options such as setting resolution, anti-aliasing, or any of the other graphics options. I've been in contact with 2k games. They don't know WTF the problem is. They want me to uninstall and reinstall Civ V and Steam. I've already done so and no help. All my drivers are up to day. I can play the game, but can't choose the settings so I don't know if they are maxed out or not. I like to max everything with my system. Playing in directx 11 mode does appear to look better than playing in directx 9 mode. It's playable and I enjoy the game, but I wish I could set fullscreen and all the graphic options to the max.
