Didn't Grand Theft Auto V already look pretty good on Xbox 360 and PS3? Yes. But it appears to look better—as it should—in the latest trailer for the November-dated PlayStation 4 and Xbox One release. Our own Gergo Vas made some GIFs to compare.
The GIFs labeled "new" were pulled from the trailer, which Rockstar says is made from footage captured from a PlayStation 4.
