Game Developers Conference 2018 is going on right now and many companies are bringing new technologies and applications to show off, including NVIDIA. Announced today, NVIDIA RTX is a ray-tracing technology that is described as bringing real-time, cinematic-quality rendering to content creators and game developers. Ray tracing involves actually following the path a ray of light takes to determine how it is affected by the materials and objects it interacts with, which is far from a trivial task. While it dates back decades, better and faster systems for it are a constant desire by many because of how difficult and time consuming the work is. Achieving real-time ray tracing is a significant feat.
NVIDIA did not work on RTX alone but also with Microsoft, enabling support for it with the new DirectX Raytacing (DXR) API. The NVIDIA GameWorks SDK will receive a ray-tracing denoiser module, to help developers wanting to add the Microsoft DXR API and NVIDIA RTX to their products. Some developers are already applying RTX, including 4A Games, Epic, Remedy Entertainment, and Unity, and will be demonstrating it over the course of the week at GDC.
One catch to RTX worth noting is it is only supported by the NVIDIA Volta architecture, which is not in a consumer-targeting product, and naturally future architectures from the company. For those of you using AMD hardware though, or more interested on the topic, that company will be presenting its own work on integrating real-time ray-tracing techniques into renderers on Wednesday at GDC.
