lol wait, ive checked your video again, and played some more minutes, you mean when you quickly move the gun from one side to the other, yes i also have what you may call "micro stuttering", it "shakes" a bit, but i wonder if this wasnt intentional due to the cold or something.
The cold?!?!?!? Ahahahahah LOL. I can see it especially when i move the visual slowly. If you are right i think this shaking is not a good idea.
