There is no game on any console that is faster than 60hz. While it may be the tv that's causing the lag it is not because it is a 60hz television.
It will help reduce the lag if you set the output resolution on the ps3 the same as the native resolution of the tv so that it doesnt have to do upscaling, so make sure that the game is being played at 720p (i'm sure it probably already is). If there is motion blur it is because the tv has a poor response rate (the speed that the pixels change colors).
What brand is the televsion? I'm expecting to hear something like Emerson, Vizio, Westinghouse or some other lower tier brand. I would stick to larger names like Sony, Panasonic, or Samsung.
Also, I assume you are using HDMI or component.
