Turning off motion smoothing is the first thing I do when I get a new TV. They used to call it frame rate, it was easy to find so I just set it at 30fps. I recently bought a new TV and couldn’t find the frame rate setting. I was afraid I would have to return it but after some googling I found out how to turn off the “Motion Smoothing”.
I think most people just accept it and get used to it, maybe we got used to the 24 to 30fps of film and are just shocked by the change. Motion blur was a problem when HD television came out, a higher frame rate was part of that fix but it makes the picture look like crap.
