Yea Forza 4 on my new (Vizio M401i-A3 SMART HDTV) has jaggies (not bad at all) mostly in the turns. The response time / lag is 0, nill, nada which is why i purchased this tv. The picture is amazingly bright which helps & hurts for the jagged lines. Thanks to "lockjaw" i'm going to try and tone down the sharpness & other options that might help to "dilute" this problem.

How about Xbox 1 anyone know if it produces jaggies as well as the 360??
