These kids (and adults!) have invested what looks like a ridiculous amount of time and energy creating a documentary on Portal's Aperture Science. Not a short five-minute web clip. Like, a 21-minute documentary.
Today, Portal with RTX is being upgraded with DLSS 4 with Multi Frame Generation, multiplying framerates, as well as the transformer model for Ray Reconstruction and DLAA, enabling even better image quality. Portal with RTX is also adding RTX Neural Radiance Cache (NRC), a neural shader that improves indirect lighting, as well as a bevy of performance optimizations.
A gameplay demo of the cancelled Portal prequel F-Stop using recreated assets features no portals, and a unique camera that duplicates items.
From GamesReviews:"Portal with RTX is a fresh look for the 2007 classic. But it's not easy to run, and the results may not impress everybody."
As long as there's science, there will be Aperture Science... making that science.. LOL
