By systematically working through these solutions, you can stop the crashes and finally enjoy Call of Duty: Black Ops 2 without interruption.

When Black Ops 2 triggers scripted events—such as the helicopter crash or the dramatic vehicle segments in the L.A. campaign level—the engine attempts to load too many dynamic graphical assets and scripts at once.

After setting this, it's a good idea to run the "Verify integrity of game cache" process in Steam once more to apply the changes fully.
