I'm seriously beginning to wonder if it is just my faster perception? I mean, we've all seen the youtube video of the demo, and that is exactly what I see when I play the campaign. I just thought there would be some more people on here with newer models that could also vouch for this affect.
The reason so many people are saying 'no lag' is because they are blind fanboys who even when presented with evidence directly in front their noses will still deny it exists. Asking people on the internet to be honest is a pretty naive thing to do.
