If you are talking 2k3, it was made with the help of Nvidia, It doesn`t detect your card, it`s just part of the game itself, that`s why you see the logo. As far as I know, you can`t change it without an .ini hack and a ATI logo inserted in the systems folder.
Single player mode is just that, single player....you can not change the map, you take them in the order they come.
Now if you start a multiplayer game, then from the options you can pick which map to start with and what maps are in rotation.
