NVIDIA just announced the NVIDIA RTX real-time ray tracing technology at GDC 2018. It promises to bring real-time, cinematic-quality rendering to content creators and game developers. Find out what NVIDIA RTX is all about, and what it means to all of us!
The Holy Grail For Photorealism
Ray tracing is the gold standard for creating realistic, lifelike lighting, reflections and shadows. It adds a level of realism far beyond what is possible using traditional rendering techniques.
Real-time ray tracing replaces a majority of the rendering techniques used today, with realistic optical calculations that replicate the way light behaves in the real world. But until today, it has been too computationally-demanding to be practical for real-time, interactive gaming.
NVIDIA RTX Real-Time Ray Tracing Technology
NVIDIA RTX is a real-time ray tracing technology that promises to deliver real-time ray tracing with high frame rates and low latency.
It runs exclusively (at the moment) on the NVIDIA Volta GPUs. Applications that run on the newly-announced Microsoft DirectX Raytracing (DXR) API will support NVIDIA RTX when used with an NVIDIA Volta graphics card.
GameWorks For Ray Tracing
NVIDIA also announced that the NVIDIA GameWorks SDK will include a ray tracing denoiser module. This suite of tools and resources will help developers increase realism and shorten product cycles for titles developed using the new Microsoft DXR API and NVIDIA RTX.
The upcoming GameWorks SDK — which will support Volta and future generation GPU architectures — enables ray-traced area shadows, ray-traced glossy reflections and ray-traced ambient occlusion.
With these capabilities, developers can create realistic, high-quality reflections that capture the scene around it and achieve physically accurate lighting and shadows.
Broad Industry Support
Industry leaders such as 4A Games, Epic, Remedy Entertainment and Unity featured NVIDIA RTX in their technology demonstrations at the Game Developers Conference 2018. They showed how real-time ray tracing can provide amazing, lifelike graphics in future games.
