I played a PS3 version and game freezes all the time. I've missed counters and trying to aim and execute an action is maddening. I don't know how many times I had to replay the part where you jump across an alley and you have to grab a person's hand. I fell at least 4 or 5 times before eI aimed correctly.
I dont know if FPS is a correct assessment of the problem. Its more like a lag or freeze.
Stuttering, yeah. The 360 version did this for me as well.
