Xbox One devs getting more graphical power, Spencer says

"More performance, new tools and flexibility"

Xbox One developers will be able to work with additional graphical horsepower starting next month, according to a tweet from Phil Spencer.

Spencer did not specify how Microsoft was able to free up this additional GPU bandwidth. It may be related to the company's decision to begin selling Xbox One without Kinect this month, as the system saves some of its graphics processing power to support Kinect commands in-game.

Xbox One's performance has seemingly faltered against PS4 since launch, as games from Call of Duty: Ghosts to Watch Dogs run at lower resolutions on Microsoft's system.

Titled 'Game On', Microsoft's E3 2014 media briefing will begin on June 9 at 9:30am PT / 12:30am ET / 5:30pm BST.
