Interesting. Assuming it's 4K on ultra details (after all, the demo was meant to impress, so it makes sense to have all the details possible), then my 1070 could be enough to run it at 1080p at medium/high settings.
With that said, my biggest bottleneck may actually be my CPU...
Please excuse my bad English.
