It was big news when Call of Duty: Black Ops was officially backwards compatible on the Xbox One console. Microsoft has been putting in and ongoing effort to make more Xbox 360 games playable on the Xbox One, and with big-name titles like Call of Duty finally seeing the light of day, it seems that their hard work is paying off.
Getting Xbox 360 games to run on an Xbox One is no easy task, however. The Xbox 360 sported a PowerPC architecture, and with it, every single Xbox 360 game was compiled into instructions that can’t be read by x86 processors, which is what the Xbox One uses. In order to accomplish this feat, Microsoft needed to build an emulator for their previous console, and like all emulators, there is likely to be a performance drop.
As it turns out though, Microsoft has really outdone themselves, and the Xbox One’s power truly shines. Not only does Call of Duty: Black Ops run just as well on the new console, but it actually runs better! The Xbox 360 version can be seen constantly fluctuating between 40 and 60 frames per second in some areas, whereas the Xbox One only has minor fluctuations, but otherwise stays capped at 60 frames per second. The fact that they were able to boost performance is praiseworthy, especially when the emulated version of the game plays at an average framerate of nearly 58 FPS when the original console could only pull off an average of 52 FPS.
Of course, no major graphical updates are coming with the release. It is the vanilla Xbox 360 version of the game you will be playing; except it is once again running on the same console that plays the latest AAA titles.
Players who own the game can simply pop their disk in, download an update, and play away. Others can grab the game from the Xbox Live Marketplace.
