DF: KZ SP= 30-40 FPS, MP= 40-60, Knack= 30-40 "Problematic Judder", Resogun= 60

[NYCrysis]

I have a 120hz monitor so maybe that's why I haven't felt any juddering. On my tv though I did feel it more often. A 30fps game on my ps3 had a bit of input lag but KZ's sp felt almost like cod 60fps on my ps3.
