You can find analysis elsewhere, all I can say is I'm surprised by how good this game looks in action. I'm playing it at 1440p maxed out. I upgraded to an SSD after playing the first few levels and am surprised by how much faster it is with an SSD. I experience no more lag except when zooming in with a sniper rifle. It seems to run just as fast as the old CoD games, but it looks far better. I can't say it looks better than BF4, but I can say it looks gorgeous. It's like a comic book almost because now it looks in the Call of Duty style, rather than striving for absolute realism like BF4 does. Frostbite is similarly much smoother with an SSD (and knocking my Ultra setting to low for post-antialiasing and taking off MSAA).
Basically, the campaign is the best CoD campaign yet. Period and better than BF4's campaign, which I like as well.
