Square Enix showcased a new demonstration of its in-house graphics technology, the engine known as Luminous Studio, running on DirectX 12 for Windows 10, at Microsoft's Build conference today.

The new demonstration, titled "Witch Chapter 0 [cry]," will probably look familiar to Final Fantasy fans. It features the same character and setting shown in an earlier real-time graphics demo, the Final Fantasy concept called "Agni's Philosophy" that Square Enix first demoed back in 2012.

"Our team has always pursued cutting-edge pre-rendered and real-time CG," said Hajime Tabata, head of the next-generation technology research project at Square Enix and director of Final Fantasy 15, in a statement. "As a part of the technical development, we created this demo using world-class, real-time CG technology with generous support from leading-edge software and hardware providers — Microsoft's Windows 10/DirectX 12 and Nvidia's GeForce GTX. The efforts from this project will power future game development as well as Final Fantasy 15, currently a work in progress."

Microsoft's Steve Guggenheimer showed off "Witch Chapter 0 [cry]" on stage today, pointing out the advancements in graphics technology on display. Guggenheimer said that demo features "8k by 8k" resolution textures, and renders 63 million polygons per scene. That's "six to 12 times more than what we could do with [DirectX 11]," Guggenheimer said.
