UPDATE:
I think I have resolved the issue as well. My issue was properly because of anti aliasing which I had maxed out. With this disabled I no longer experience the stutter at all.

I have the exact same issue with my game. I've just build a gaming setup for this game because it was unbearable to play the game on my laptop because of low fps. I've never experienced this issue on the laptop, probably because it was so jerky to behin with.

My setup is as following:
OS: WIN7 ultimate
MB: Z97-A
CPU: INTEL I5-4670k 3.4 not OC'ED yet
COOLER: COOLER MASTER HYPER 212 EVO
ram: 2x 4gb Cosair vengence 1600mhz
HD: ocz vertex 4 128GB SSD
PSU: XTX core pro 550w
GFX: GTX 770 GAINWARD 2gb

i
I get various fps with this setup all ranging from 25-60fps all dependant on the situation

I've noticed its worst when I'm doing a command either shooting or fast camera turn when an undetermined time has elapsed ingame as the previous poster. Perhaps it could be issues with in the latency of client/server requests?
Hopefully this issue will be resolved in the near future
