Infinity Ward executive producer Mark Rubin revealed that the Xbox One version of Call of Duty: Ghosts would run at 720p native resolution upscaled to 1080p while the PlayStation 4 version will run at 1080p natively.
According to Rubin, no single bottleneck forced them to reduce the Xbox version's resolution. "It was more about resource allocation," he explained. "The resource allocation is different on the consoles. That huge web of tangled resources, whether it's threads-based or if it's GPU threads or if it's memory - whatever it is - optimisation is something that could go theoretically on forever."
Microsoft insists that Xbox One performance is on par with that of PlayStation 4, but today's announcement only serves to confirm everybody's suspicion that this is not entirely true.
Nonetheless, Rubin believes that they haven't tap into all Xbox One resources yet and there is still room for optimizations and improvements in subsequent titles."Look at Call of Duty 2 versus COD 4," he noted. "It was a massive leap forward in graphics, and that's just because it takes time to get through this."
