I recently updated my nVidia drivers. Since then, when I start Civ 5 I get the intro movie, but then the screen goes black. It shows up properly when previewing it by scrolling over the bottom bar on the desktop view, but when I switch to it it's only a black screen.
I managed to get it to be visible either by going into windowed mode, or by choosing a lower screen refresh rate (60Hz, anything above will give a black screen). It was working fine at 144 Hz before. I tried to uninstall and re-install it, but no change. I'd be grateful for any help!
I might add that since that update I have also had problems with Far Cry 4, which also can't be run in full screen mode.
