BeefJack: "Sure, there were plenty of negative reactions to it not taking very long to finish, but as Erik Wolpaw notes himself, “without the constraints, Portal would not be as good a game.” It’s hard to disagree, not least when the end result is heaven on a DVD-ROM. Those two, three hours delivered more inventiveness and emotion than a dozen blockbusters stuck together."
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.

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."
Good summary of why the first game was a corker. It's easy to feorget now, but it looked like this tiny game they'd added to fil out the Orange Box when it was released. Now look at it :)
Seriously can't wait till my Steam copy unlocks!
