With vsync on or off it stays at 30fps and sometimes dips to 29fps and I do notice stutters at time. I ran fraps and it said I was running at 30fps most of the time but on occasion it would dip to 29 to 30fps... Ridiculous. And who ever said you don't notice any stutters at 30fps on some games are a liar. I know that smoothing graphics options in some games hide the stutters but Transformers does not have that from from what I'm seeing.
