Turn the Depth of Field to low. I had the same issue. Depth of field is wierd and really messes with the FPS.
That worked great however it makes me wonder is my pc not strong enough to handle Black Ops 2 at max settings or is it a bug in the game
Dude, it's a bug. My machine is half of yours and runs it fine at max.
Yea it would have be a bug.
In the first Black Ops the almost the same thing would happen, but it was an FPS spike (downwards) so it is almost like a tiny freeze when you aim down your weapon and fire, close to the same time. However turning off settings didn't help that one, Its nice to know atleast turning DOF to low will help in this one.
Yeah, happens to me sometimes too. Thankfully the MP and Zombie mode run ridiculously smooth (60-150 FPS) so even when my FPS drops a bit for a short time i bearly notice it still i hope it gets fixed, I'll try to see if Deph Of Field really is the issue with this once i get home in 2 days.
