Portal, while a fantastic game, is guilty of committing one of video games' greater taboos: it left players wanting more. Not due to how mind-blowing the experience was, but because it was too short. Sure, you could play through it again and again. But after the 80th time, redundancy sets in.
Chasing yourself in the corner loses its fascination. Euthanizing your Weighted Companion Cube may grow to become second nature. And dealing with GLaDOS may become no more irritating than working with Vista. All that once captivated, seemingly loses momentum.

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."
More portal please. I miss my companion cube.
sorry, just don't care for it.
