Xbox One launch titles seem to be a favouring a bizarre range of resolutions. Ryse: Son Of Rome has now slotted in between Killer Instinct's 720p target and Forza 5's native 1080p, rolling out with a 900p internal resolution that's upscaled by Microsoft's hardware.
"Update from team," tweeted Microsoft's devices and studios chief Aaron Greenberg tweeted earlier this morning. "Studios Group Forza 5 is native @1080p, Ryse is native @900p, but Xbox One upscales all titles to 1080p & they look amazing."
This message was in response to an error made yesterday, when Greenberg erroneously suggested that both Forza 5 and Ryse both boast a native 1080 resolution.
The scattershot variety of native resolutions (as mentioned, from 720p to 1080p and even Dead Rising 3's "dynamic resolution" that fluctuates to ensure 30 FPS) suggests that developers are having trouble keeping up with the constantly-changing drivers and hardware configuration of Microsoft's machine. Before you get too worried, though, this happens at practically every console launch.
So long as games run at a decent clip and look good after upscaling, we probably won't sweat the small stuff... but our concerns still lie with Ryse: Son Of Rome's gameplay, not the graphics.
