I was wondering what the online state of this game is? I was holding off until the patch had come out. From reading the forums (this and other) it seems as though the lag and framerate issues have been fixed. If this is the case then this will be a purchase for me this afternoon.
It stopped the small stutters for me when I was walking along but get into a fire fight with a few other people and the game grinds to a halt.
It still freezes here and there. It causes annoying deaths from time to time, perhaps once a match, if that. In the end though it's not distracting enough to make me do, badly. I still do very well for myself on the game, and I'm still able to have a lot of fun playing it.
