Portal RTX, Nvidia’s Latest Technology Showcase, Is Released
Presented this summer at the same time as the announcement of the latest graphics cards from Nvidia, Portal RTX was released as planned yesterday. A true showcase of Nvidia’s technological advances, this remaster of Valve’s classic allows you to admire all the ray tracing functionalities concerning light management, to which are added some new features: Shader Reordering, Opacity Micromaps, RTXDI and above all a lighting entirely managed by ray tracing. That is to say, each ray of light is truly created individually, without any other cheating to gain performance. As with the RTX remaster of Quake II, the guys at Nvidia, in collaboration with Valve, have redeveloped the game on a newer engine (RTX Remix), capable of accommodating all these new effects.
In parallel with these magnificent rays of light, Nvidia also presented DLSS 3, limited to owners of RTX 40XX cards. As a reminder, this technology theoretically makes it possible to gain in performance thanks to upstream work on AI, machine-learning, etc. And, indeed, according to the analyzes of Tech Power Up, the DLSS 3 would make it possible to double its number of frames/s once activated. Fortunately, because without DLSS 3, an RTX 4090 does not run at 60fps at 2560×1440! Holders of older cards will still be able to enjoy the game thanks to DLSS 2, which will also save a few frames/s.
Still, the images of the game with these new graphic effects give a very beautiful light to the whole. Unlike many titles that try to highlight ray tracing with irrelevant videos, here we can clearly see the difference. We can’t wait to see a new game with such developed ray tracing. Finally, only if the cost of entry to these technologies becomes more affordable.
Portal RTX is free on Steam for anyone who already owns the base game — presumably that means our entire readership.
