An in-depth look at the bonus single-player campaign Portal included in the Half-Life 2 Orange Box, from GDC 2007 (Parts 1 and 2)

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."
It's Great!
Ok wrong article...grr
Did the developer say that all 5 games were on one disc? I hope that includes the 360 version. If it did, that would be unreal.
