Update, 4:38PM ET: We've spoken with a representative from Microsoft, who provided the following statement: “Xbox One fully supports native 1080p output at 60 fps. It is up to individual developers to determine what resolution best fits their design goals. At launch, Xbox One will present all titles at 1080p—whether natively or upscaled.†It’s worth keeping in mind that just because a box can output at 1080p doesn’t mean it will. For instance, we already know that Ryse – a high-profile launch title — will be running at 900p. The further we get into a console’s life, though, the more experience developers will have with that console, and can figure out methods to get the most out of it. The representative said they could not comment on the rumor regarding the stress test boxes outputting at
900p.
