So, just  kinda throwing this out there to see if anyone else is experiencing screen tearing in the game.   Baaaaad screen tearing too.    I'm not sure about the PC/360 versions however I've played the Ps3 version and most notably on the dialog sequences I can' often spot it.  
 
Even in a few areas turning the camera  causes tearing. 
 
Just trying to see if I'm crazy or if  this is actually as bad an issue as I think it is at least with the Ps3 version. 
 
I've also had multiple freezes on top of the screen tearing.

I've not noticed any tearing, but definitely a whole lot of crashes. This game crashes more than New Vegas ever did. lol

I have actually not noticed one single screen tear in 29 hours of play on the 360, nor any freeezing. Actually I haven't really hit any bugs yet either except for one - a battle in Kirkwall ended with one enemy left and when the cutscene was over, he was there waiting to be killed.  
 
I was looking at the Lens of Truth on DA2 though and the tearing percentage is horrendous on the PS3. Like almost 9 percent horrendous. Then again I find that site always favors the 360 anyway so I'm not sure if they're to be taken srsly. But what you're saying seems to back it up
