I'm about 15 hours in and I have noticed some screen tearing. The most pronounced instance is when the main start menu comes up. Death is shown wherever your last save was (very cool - makes the title screen different every time) and as the camera swings around, you do see some minor screen tearing. I've only seen it once or twice during actual gameplay, though.
If you played the 360 version of the original, you remember the screen tearing there. It isn't nearly as bad as that one was pre-patch.
It isn't exactly what you asked, but loading is a problem. It is not uncommon to be running along (mostly in the overworld, not as much in dungeons) and have Death just freeze in place while a little loading spinner appears on the left side of the screen. It happens a LOT when going from one "area" to the next, and it never gets any less irritating.
