Microsoft is building its own cloud gaming service. Company officials demonstrated a prototype of the service during an internal company meeting today. Sources familiar with the meeting revealed to The Verge that Microsoft demonstrated Halo 4 running on a Windows Phone and PC, both streaming the game from the cloud. We're told that the concept service runs smoothly on both devices, and that Microsoft has managed to reduce the latency on a Lumia 520 to just 45ms.
This is quite impressive; especially the 45ms latency. I would REALLY love to play Halo 4 on my PC.
