Vladimir Koylazov has published a blog post discussing the implications of NVIDIA’s RTX hardware for traditional Raytracing, GPU rendering & V-Ray.
The article discusses the ways in which traditional rendering can benefit from the new hardware and share details on a customised version of V-Ray GPU that’s experimenting with the new cards. Vlado also discusses their real-time ray tracing Lavina project; and NVLink bridge, now compatible with gaming cards, that enables multiple GPUs to share their memory.
Finally, Vlado concludes: “Specialized hardware for ray casting has been attempted in the past, but has been largely unsuccessful — partly because the shading and ray casting calculations are usually closely related and having them run on completely different hardware devices is not efficient.
“Having both processes running inside the same GPU is what makes the RTX architecture interesting. We expect that in the coming years the RTX series of GPUs will have a large impact on rendering and will firmly establish GPU ray tracing as a technique for producing computer generated images both for off-line and real-time rendering. We at Chaos Group are working hard to bring these new hardware advances in the hands of our users.”

Lavina is very impressive considering the dense geometry! I read some comments hating on a video recently showing the result of the lake flyover. But the zoom-in on the geometry in the last video here is quite telling! Also check out the navigation inside the office, no light baking there and many millions of polys. One GI bounce.
