If you ever want to educate yourself on the complex intricacies of resolution and framerate comparisons, there is no better place in the world than Digital Foundry. Instead of measuring shticks based on the personal bias of a given brand (ex: PS4 v Xbox One), these guys provide actual numbers and concrete data. This time, their focus is on the upcoming behemoth shooter, Call of Duty: Infinite Warfare and how it will perform on Sony's incremental upgrade.
Overall, the game is an improvement regarding its visuals, but its mild framerate drops during on-screen explosions are still a factor. As a whole, the game maintains a constant 60 FPS, so it will only be noticeable to gamers who really scrutinize.
Call of Duty: Infinite Warfare's multiplayer beta begins in about a month on PS4 and Xbox One, and while it was thought that the Call of Duty 4: Modern Warfare Remaster (available to purchasers of the Collector's Edition), it may end up being sold separately sometime in the future.
