RTX Portal Announced

Included in NIVIDIA's announcements today is the announcement of Portal with RTX, an updated version of Valve's classic puzzle game that takes advantage of the horsepower of NVIDIA's RTX graphics card to add full ray tracing support. This page offers a World Premiere Trailer and says this can be wishlisted right now on Steam (thanks jacobvandy). Here's word:
Portal with RTX exemplifies the incredible power of our new, beyond fast GeForce RTX 40 Series graphics cards, and the capabilities of our NVIDIA RTX Remix modding platform. Every frame of gameplay is upgraded with stunning full ray tracing, new, hand-crafted hi-res physically based textures, and new, enhanced high-poly models evocative of the originals. Performance is accelerated with NVIDIA DLSS 3, allowing the game to run incredibly smoothly, and system latency is minimized using NVIDIA Reflex. And it was all built collaboratively by NVIDIA Lightspeed Studios.

In Portal with RTX, full ray tracing transforms each level, enabling light to bounce and be affected by the scene’s geometry and materials. Every light is ray-traced and casts shadows, global illumination indirect lighting naturally illuminates and darkens rooms, volumetric ray-traced lighting scatters through fog and smoke, and shadows are pixel perfect.
