Phil Spencer says 'framerate is significantly more important than resolution.'

The Xbox boss doesn't believe that the well-publicised performance gap between Xbox One and PS4 is particularly significant.

The Microsoft executive spoke to CVG about the issue at gamescom. "We announced that Destiny will have the same resolution and frame rate on Xbox One as PS4. There are a long list of games. Reaching parity with our partners has been important," he said.

He continued, "But in the end I don't want it to be about a number, because 1080p isn't some mythical, perfect resolution. Frame rate to me is significantly more important to gameplay than resolution and the mix of those two which brings the right art style and freedom, whether it's on PlayStation or our platform."

He went on to cite Sony's PS4 exclusive The Order 1886, which renders at the 1920x800 resolution to give it a cinematic feel. Spencer sees this as an example of artistic freedom, rather than forcing a developer to reach a number that is perceived by the public as ideal.

"Clearly some genres like with racing sims like Forza, hitting 1080p/60fps is important,' he conceded. "So there are certain genres where there's an expectation, but there are also other genres where I'd rather use the cycles to put more effects on screen or better lighting. I've got to put the tools in the hands of developers."
