NVIDIA Extends DirectX Raytracing (DXR) Support to Many GeForce GTX GPUs
NVIDIA this day announced that it’s extending DXR (DirectX Raytracing) toughen to so much of GeForce GTX graphics devices previous its GeForce RTX series. These consist of the GTX 1660 Ti, GTX 1660, GTX 1080 Ti, GTX 1080, GTX 1070 Ti, GTX 1070, and GTX 1060 6 GB. The GTX 1060 three GB and decrease “Pascal” devices build not toughen DXR, nor attain older generations of NVIDIA GPUs. NVIDIA has implemented true-time raytracing on GPUs with out in actuality ultimate ingredients such as RT cores or tensor cores, by basically implementing the rendering path through shaders, on this case, CUDA cores. DXR toughen will possible be added through a fresh GeForce graphics driver later this day.
The GPU’s CUDA cores now comprise to calculate BVR, intersection, reflection, and refraction. The GTX Sixteen-series chips comprise an edge over “Pascal” despite lacking RT cores, as the “Turing” CUDA cores toughen concurrent INT and FP execution, permitting more work to be carried out per clock. NVIDIA in an intensive presentation listed out the forms of true-time ray-tracing effects available by the DXR API, namely reflections, shadows, developed reflections and shadows, ambient occlusion, international illumination (unbaked), and combinations of those. The company establish out detailed performance numbers for change GTX 10-series and GTX Sixteen-series GPUs, and compared them to RTX 20-series SKUs that comprise in actuality ultimate hardware for DXR.
Update: Article up thus a long way with extra take a look at data from NVIDIA.
