Hey, I have an XFX GTX 260 Black Edition and yes I am getting some annoying stutters too. I asked the same question about how the fps never go above 60, even when not forcing Vsync through nvidia control panel, and got a sarcastic answer. My problem is I dont know how much stuttering I should get at about 45 fps. It is pretty smooth when at 60 fps, and this seems like a game should act, no(slight) stutters at 60 fps and it should start slowing down when the fps drops, but it seems to me I am geting too much stuttering for 45 fps, I never drop below 40. But some other people on here are saying they are getting horrible stuttering even at 60 fps. So I am wondering also why the fps don't go above 60 and why your little brother's 9500GT can play this like you say.
