4A Studios has just announced the Enhanced Edition of Metro Exodus for PC with an even more advanced lighting and ray-traced pipeline. While the existing game already makes use of ray-traced global illumination to create realistic lighting and ambient shadows, the reflections are still rasterized. Furthermore, the game features the original DLSS implementation which isn’t quite as good as DLSS 2.0 and often leads to loss of detail and sharpness.
Metro Exodus Enhanced Edition on PC will feature an all-new Fully Ray Traced Lighting Pipeline with Ray Traced Global Illumination, Emissive Lighting, path-traced reflections (RT with infinite bounces), and an upgraded temporal upscaling algorithm (primarily for AMD systems).
As you can expect, the inclusion of path tracing in an already taxing game will make it quite the monster. As such, you’ll at least need an RTX (or AMD Radeon RDNA 2) graphics card to even run the Enhanced Edition of Metro Exodus. With the details cranked up, you’re probably gonna need a top-end GPU and even that won’t be able to run the game at higher resolutions without the use of DLSS 2.0.
The next-gen PS5 and Xbox Series X consoles are essentially getting the existing PC port with improved textures and some other optimizations and improvements.
