Just purchased Civ V from latest Steam sale and trying to run the game in native res fullscreen (option is available in the menu) but refuses to display properly. In fact, all resolutions beyond a certain point do not render correctly in fullscreen mode (see attached screenie). The max available res in windowed mode - which works great, all windowed mode res' do - is 1920x1200 (which oddly enough fills the whole of the native res desktop space). Any ideas? I'm running Win7 64-bit with the 306.97 drivers. Thanks!
