Was it in fullscreen or window mode?
I run on a laptop with a Nvidia GTX 950m, 16 GB RAM, and an i5 processor. My menu does not stutter at all.
You could try verifying your cache also, and see if it stops stuttering if you lower your settings.
If you have already tried what I have said, then I am actually not sure what could be causing the stutters.
Unless, your computer is using more than 8 GB of RAM, while running advanced warfare. Usually, when a game stutters like that, it could be due to not having enough RAM.
