Square Enix, the studio responsible for the famously pretty Final Fantasy series, routinely creates tech demos for the latest and greatest gaming systems, and this week it added one more to that repertoire. During Microsoft's BUILD dev conference, Square Enix showed off a real-time DirectX 12 tech demo called WITCH: Chapter 0 [cry]. True to its name, this demo includes a crying woman -- Agni from previous Square Enix tech demos -- and all of the wonky facial animations that come with such an activity. WITCH features 63 million polygons per scene, "six to 12 times more" than what was possible with DirectX 11, Microsoft says. Check out the real-time demo below and note that while the animations certainly are pretty, there isn't much going on in these scenes in terms of AI or NPC population.
