The Xbox One version of Titanfall, at least in its current beta form, does not run in native 1080p. Instead, Respawn Entertainment community manager Abbie Heppe told the Titanfall Blog that it currently runs in 792p, but could be closer to native 900p at launch next month.
As the Titanfall Blog points out, Titanfall's 792p resolution is not that outlandish as it may seem. Many games run at non-standard resolutions and then are upscaled to more common benchmarks like 720p or 1080p. In the case of Titanfall, 792p would be upscaled to 1080p on your console.
Titanfall's frame rate remains a mystery, though producer Drew McCoy told Eurogamer last summer that "frame rate is king." For more on Titanfall, check out GameSpot's video preview below.
Microsoft director of product planning Albert Penello responded to the 1080p/60fps debate recently, saying, "these little things get way overblown."
The game's beta launches this Friday for Xbox One and PC before its full release for those platforms on March 11. The Xbox 360 iteration will launch two weeks after Xbox One and PC versions because developer Bluepoint Games needed more time to polish the experience.
