I have the same problem as well,
Its not a hardware issue, as I have played many other maps outside of career mode with success.
However, every second stage of a map in career mode all the map textures go black. Only the start lights are visible and I am still able to hear the audio of my car.
I thought it was just a specific map problem, so I retired the event and chose another map. The first stage of that map was functioning well with no problems, then once the second map comes into rotation, its just another black screen texture map. Its just unplayable man.
