In an interview with Eurogamer, Blizzard Entertainment's production director John Hight discussed the original 900p resolution for the game. "We did find it challenging early on to get it to 1080p," Hight said. "That's why we made the decision to drop to 900. 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."
Considering the early criticism of early Xbox One games being unable to reach 1080p resolution, while the PlayStation 4 could, it was believed Microsoft was issuing an ultimatum to developers, based on Hight's comment. However, Spencer took to Twitter to further explain what happened regarding "Diablo III." "We didn't force any game to ship at 1080p. We work with devs to make the game they want to make on XB1." Spencer later tweeted, "Diablo III was coming through during GPU increases in June, was good partnership to create a great Diablo on XB1." Making matter even clearer, Spencer stated studios like Blizzard Entertainment are ones who have final word on how it ships a game for Xbox. "They know their games better than I do."
"Diablo III" is currently available for the Xbox One and Xbox 360, along with PlayStation consoles and PC. To achieve 1080p resolution, a "Day One" patch is necessary to download on the Xbox One. Boyd Multerer, director of development for Xbox, was quoted in the official Xbox magazine as saying to expect more 1080p games on Microsoft's latest video game console.
