It is "physically impossible" for the Xbox One's graphical performance to catch up to what the PS4 is capable of, Just Add Water CEO Stewart Gilray has stated in an effort to dismiss inaccurate reports attributed to Oddworld creator Lorne Lanning.
A report on Xbox Achievements was titled, "Performance Gap Between Xbox One And PS4 Will Disappear, Says Oddworld Creator," but this is said to be inaccurate.
"Actually that is NOT what he said," Gilray told Worlds Factory. "I spoke to Lorne afterwards and what he meant when speaking to that guy was that budgets, schedules and perceivable differences would narrow, NOT that the Xbox One performance is improving to align with PS4, that is just physically impossible. The PS4 has MORE COMPUTE units, and faster memory and a whole bunch of things, that would make that physically impossible to happen."
It has been reported that Xbox One will see benefits of DirectX 12, but it's unclear how much performance will be gained. Likewise, Microsoft is working on freeing up the GPU resources currently held back for Kinect and OS functions.
