Screen tearing can best be described as the entire screen not updating at the same time, so when you turn, you'll briefly see parts of the screen not updating, and in between those parts you'll see a little line, or "tear" separating them. I tried filming yesterday but, of course, the part I filmed didn't explain my point enough. And yes, I'll make a point to not show any spoilers. You may see a new Italian town, but that's about it.
