> Microsoft was I intrigued and worked closely with that vendor to design the next-generation Direct3D API. I've heard "accusations" that it was actually the inverse. Microsoft and that vendor were working together on next gen consoles, including the new D3D12 API. But Microsoft weren't planning to release it on windows until long after the xbox one released. The vendor wanted something to show off now, so they pulled together Mantel in a reasonably short time-frame and announced/launched it before D3D12 was even in an announceable state. I have idea if these "accusations" are true, it's just what I've heard.
