Technical analysis of the Destiny beta!
"Put side-by-side, the Xbox One produces slightly fuzzier detailing on these elements, though the actual quality of textures - and filtering - is a complete match between the two."
"Destiny's beta campaign missions show a rock-solid, v-synced 30fps on both PS4 and Xbox One. Even in the hectic multiplayer mode, as appended to the end of this video, the engine runs perfectly."
"The only bug-bear is the 900p versus 1080p differential, where the PS4 benefits from a clearer image. However, based on footage released of the 1080p Xbox One build so far, this is to be corrected with no apparent sacrifices to visuals elsewhere. Where performance is concerned, we'll have to see nearer release whether this 1080p playback is achieved with no impact to the game's smooth, consistent frame-rate."
"All in all, it's a very encouraging scenario. Both next-gen consoles run at the same levels of world detail in this early build, with Xbox One also a match for the PS4's stable frame-rate."
