"The thing that's really incredible about what you're seeing is just the density of data that's involved in this," Shewchuk said.
In a bid to show that the demo was not pre-rendered CG, Shewchuk opened the free camera to look around the scene in real-time, as well as make various changes to the lighting.
Shewchuk claimed that each scene renders about 63 million polygons. "That's about six to 12 times more than we could do with DX11," he said.
He went on to claim that the textures were 8K by 8K, and that "every piece of hair is being rendered as a polygon - this isn't surface map stuff. I think it's an incredible example of just how far people are pushing big data."
Nvidia said the demo was "running on four of our flagship GeForce Titan X GPUs," and described it as a "stunning example" of what can be done with Microsoft's next graphics API.
Direct X 12 is due to arrive with Windows 10, which is rumoured will release in July, though no official date has been set.
