Xbox One's day one patch update for Diablo III: Ultimate Edition, pushing the title up to 1080p, was originally instigated by Microsoft themselves, a Blizzard spokesperson has said.
John Hight, who worked as production director on Diablo III, stated that while they'd achieved 1080p during development, they "were finding it challenging" to maintain that framerate.
"That's why we made the decision to drop to 900," he stated during a conversation about the title at Gamescom. "That's what we demoed and were showing around E3 time. And Microsoft was just like, 'This is unacceptable. You need to figure out a way to get a better resolution.' So we worked with them directly, they gave us a code update to let us get to full 1080p."
