Microsoft has had plenty to say about Windows 10 over the past several months leading up to its Build conference that wraps up today. While we've heard some details about DirectX 12 and how it'll be exclusive to Windows 10, we haven't yet seen it in action... until now.

Microsoft commissioned Square Enix to build a real-time "Art&Tech" demo to show what'll be possible with DirectX 12. Using a high-end Digital Storm system with four graphics cards, the demo - dubbed Witch Chapter 0 [cry] - is incredibly impressive.

The presenter was able to run through the scene manually and adjust various settings like lighting on-the-fly. We're told that there are over 63 million polygons per scene which is roughly six to 12 times more than is possible in DirectX 11. Perhaps most impressive is the hair as every single strand is being rendered in real-time.

Keep in mind, however, that this is just a tech demo and it's running on a very high-end system. Even still, it gives a glimpse into the future of PC gaming which has already come a very long way in a relatively short amount of time.

Over time, we'll reach a point where this sort of performance is possible via a single, affordable graphics card. But for now, all we can do is dream.
