As far as I've understood this (and I've done a bit researching, although Im not giving any guarantees of whether Ive understood the whole system perfectly sooo... don't quote me) the technology works a bit like google (or with similiar algorhytm). And the speed of google is based heavily on the fact that the data is well indexed. However, in this case we're talking about game worlds that presumably are changing (this is why there are only static worlds made with this technology in the videos I've seen at least) which should basically destroy all hopes of running this smoothly. Show me a computer that can calculate moving millions of cloud points @ let's say... 60 times in a second?
This company seems like it's only looking for a quick cash in from some major company who fail to realize that this kind of technology won't have any practical use in many many many years.
Please feel free to correct me if I'm wrong
On a sidenote; the graphics look amazing and as far as I know most of the stuff you see on the video has been made by some programmer and not actualy artist
