As clever as this rendering tech may be, polycounts were already on the way out as a limitation for game assets—it sounds awesome that billions of polygons can be used, but it it doesn't mean we're going to be able to render film-quality environment scans with ease. To get results like you see in the tech demo you'll need some good hardware, but it is within reach of today's gaming PCs.
"A number of different components are required to render at this level of detail," says Sweeney. "One is GPU performance and GPU architecture to draw an incredible amount of geometry. You're talking about a very large number of teraflops being required for this. The other is the ability to load and stream it efficiently."
Would this demo run on my PC with a RTX 2070 Super? Yes, according to Libreri, and I should get "pretty good" performance. For comparison, the PlayStation 5 GPU the demo video was captured on achieves 10.28 teraflops, while the RTX 2070 Super hits just over 9 teraflops.
