The recently released
Portal: Prelude RTX used a new version of NVIDIA RTX Remix that improved performance and the quality of path tracing for older graphics cards. Later this Fall, we’re bringing those optimizations and enhancements to
Portal with RTX, alongside an upgrade to
NVIDIA DLSS 3.5, which introduces a new feature called Ray Reconstruction that uses AI to improve ray tracing image quality.
In
Portal with RTX, textures are enhanced as Ray Reconstruction intelligently accumulates engine data and information across multiple frames to produce a more accurate and clear image. With existing rendering techniques, full ray tracing could struggle to resolve multiple photons of light bouncing against thin materials, like metal fences, or highly reflective surfaces. This could cause excessive shimmering on thin surfaces and light instability or “boiling” on reflective walls. But with DLSS 3.5’s Ray Reconstruction technology, each fence appears stable no matter how much light is illuminating the thinnest of its meshes.
Lights and reflections update faster and more accurately, too and each crevice in every room is lit with clarity, making the test chambers of Aperture Laboratories look as they would in the real world.
