Screen Tearing

Another example, Gears of War 2 again analyzed by the Digital Foundry guys.

"In the case of the Gears clip above then, there are 3894 frames in the original capture, 2088 duplicate frames and therefore an average frame rate of 29.7fps. Check out the full analysis of this clip by clicking here. However, out of that same sample, there are 845 torn frames - a sizeable 21.7%.
The extent of how impactful that is depends on many factors; the sensitivity of the human eye, and where the tear actually is being most important. If the tear is at the top of the screen, more often than not, it’s not noticeable (see Pure, Mirror’s Edge and WipEout HD in 720p mode on PS3)."

I went through it in slow-mo and found so pretty good examples. Screenies like below should never be allowed to happen in a commerically shipped game:

 

You should have read this part:

A clip of Gears of War 2 I decided to analyse. With streaming video, the 60fps capture is decimated down to 30fps, losing every other frame. So torn frames are either removed altogether, or are displayed for twice as long as they should be. Such are the limitations of internet video - it can’t be used as a basis for judging screen tear…

Just watching the whole video in real time, I noticed 0 tearing.  Sure it could be there, but during standard play it is not noticeable.  Nothing anywhere near what I saw in Crysis or Blue Dragon.
