Volta only had Tensor cores which are used to accelerate matrix operations used for deep learning. It's the reason we didn't see Volta based gaming cards. Instead they made a dedicated core to accelerate BVH and ray / triangle intersection calculations called RT cores. Turing and Volta have Tensor cores which nVidia uses to denoise an image after it's Ray Traced.

Tensor cores are doing great and it's the reason they keep landing AI based deals. From compute cloud solutions to self driving cars.

nVidia's plan from when they first launched OptiX v1.0 in Nov 3, 2009 was to utilize a hybrid ray tracing method in gaming.

You can see them here explaining the use cases in 2010:
