If you got the map by joining a server delete it and install it yourself instead as it's known for causing issues sometimes.
Also make sure there aren't any mod in the Activision mods folder.
You might also repair your game, just in case.
Finally go take a look at the map on the internet (on websites where you can download it), if there are instructions for the map like disabling a certain video settings then do it.
