Nvidia and 4A Games have posted a very in-depth video of the upcoming Metro Exodus, designed to show off both the ray-tracing capabilities as well as just how the technology works. RTX ray tracing is incredibly resource intensive with several hundred million rays of light being rendered at any given moment, all happening in real-time. Light is thrown from light sources, bouncing and refracting exactly as you'd expect it to. Different light sources also impact one another, which is a marked difference from standard rasterized illumination techniques.
The extensive gameplay footage shows Metro Exodus running with RTX both on and off, providing an excellent side-by-side comparison of what the technology can off you. Whether you think that’s worth $1200, well, only you can decide. The benchmark below is running on a GeForce RTX 2080 Ti.
“The results presented here demonstrate a technique that simplifies and improves upon the previous generation of techniques by combining disparate rendering technologies into a single unified algorithm,” explains 4A Games’ Ben Archard.
“This new ray-traced global illumination algorithm benefits from access to a wider range of scene information and greater physical accuracy. It enables the creation of more realistic and more believable environments in potentially shorter development times.
“RTX assists in creation open, natural environments as well, lit appropriately according to the contributions from sunlight alone.”
This video also provides confirmation that ray-tracing will be supported by Nvidia GeForce RTX 20 Series graphics in Metro Exodus from launch day, on February 22nd, 2019.
