Hi,
The engineer who pulled this together is at Siggraph now, so we won’t get definitive answers soon. As originally written the demo required volume tiled resources, hence DX11.3 (if memory serves) and Win10. However we relaxed the VTR requirement at the last minute, so I think it should run on any Maxwell or Pascal class card, and brand-B GPUs as well if they support 11.3. There could be a bug though.
