These new ray tracing additions in game engines should speed up the development process for developers as well as being accessible to anyone who uses the platform. He later went on to talk about how impressive the industry has been at adopting these new technological additions, before finishing with: "it all points to an exciting future for gamers".
For decades, NVIDIA has been working towards the dream of real-time videogame ray tracing.
The graphics chipmaker announced Monday at GDC 2019 it will enable DirectX ray tracing (DXR) on some of its older graphics cards with its Pascal architecture via a driver expected in April. Games that support the Microsoft DXR and Vulkan APIs are all supported.More news: Rs 13000-crore PNB scam accused Nirav Modi arrested in London

GTX cards will instead perform ray tracing calculations such as BVH (Bounding Volume Hierarchy), and ray / triangle intersection on their shader cores, which already handle other tasks in traditional rasterised rendering.
The graphs look at GPU utilization on Pascal, Turing with RT cores disabled (via a special software setting to show GeForce RTX 2080 performance without the use of RT Cores), and Turing with RT cores and DLSS enabled.
NVIDIA GameWorks RTX is a comprehensive set of tools that help developers implement real- time ray-traced effects in games. The obvious implication is that it may be possible to achieve real-time ray tracing without dedicated cores, thus potentially leaving Nvidia's RTX customers wondering why they have paid for the privilege, and those using existing graphics cards wondering if they might be able to get in on the action without a costly upgrade. It will support ray traced effects like area light shadows, glossy reflections, ambient occlusion and diffuse global illumination. Cards at the low-end of the Pascal scale will only offered the most basic of ray tracing features and will certainly be limited to 1080P as a resolution. "Now millions of developers working in Unity can achieve unbelievable graphics with lightning speed", Nvidia vice president of Professional Visualization Bob Pette said. Until now, Ray Tracing was exclusive to NVIDIA's RTX series of graphics cards, but not anymore.
