rtx

Nvidia RTX is a high-end graphics rendering development platform created by Nvidia, primarily aimed at enabling real time ray tracing. Historically, ray tracing had been reserved to non-real time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on rasterization for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows, reflections. RTX runs on Nvidia Ampere- Volta- and Turing-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing) on the architectures for ray tracing acceleration.In March 2019, Nvidia announced that selected GTX 10 series (Pascal) and GTX 16 series (Turing) cards would receive support for subsets of RTX technology in upcoming drivers, although functions and performance will be affected by their lack of dedicated hardware cores for ray tracing.Nvidia worked with Microsoft to integrate RTX support with Microsoft's DirectX Raytracing API (DXR). RTX is currently available through Nvidia OptiX and for DirectX. For the Turing architecture, it is also available for Vulkan.
