No. Tensor cores have nothing to do with ray tracing - unless they are being used to denoise the image like in DLSS "ray reconstruction".

RT cores are being used of course when an application is requesting ray tracing through DXR.
If it's DXR (or whatever similar functionality is called in other APIs), it uses RT acceleration of the GPU. If it's some custom software R&T it doesn't.

- If a game is using DXR API (or VkRT, or whatever Apple has) then this workload can be done by the GPU RT h/w whether it's "RT cores" or "RT Accellerators" or some other brand name for it.
- It can also be routed by the GPU driver to be done with a custom driver-side GPU compute shader which is how Nvidia enabled DXR support on Pascal GPUs but this is mostly irrelevant now.
- If a game isn't using DXR but is using DX and does some sort of ray tracing then it is being done by game's own GPU compute shaders.
- Games can mix both at the same time of course and many of them tend to do it in one way or the other.

So the game doesn't actually look the same on non-RT h/w as it just disable GI to run on it. So much for s/w solution and RT h/w being a requirement I guess. It's basically similar to how any other game which runs on non-RT GPUs while using RT h/w for something behave.

Actually double post - why not!?
Basically, on NV cards using NV Profile Inspector there is a flag that exists to deny access to/turn off DXR. You can check it out yourself if you want, looks like this:
If you turn on this flag, DXR games will not boot with errors usually given about unsupported hardware. Or the options will not show up or be greyed out in the menu...just like on any pre-DXR hardware.
Having that to "RT Disabled" forces avatar to run the software path, see below:
Minus some differences in the environment that occur due to have to reload the save and manually position the camera, to me the visuals look pretty similar. Indoors in a very small environment, software GI is not too much slower. Outdoors in the jungle, the difference in performance is quite substantial.

Hm, that's a bit embarrassing on CB's part.
I do still wonder though if the game behaves differently on a card which doesn't support DXR at all.
Also there seem to be some difference in shadowing between your screenshots. But maybe it's just the clouds/trees affecting the sun light.
The game cannot access DXR so it is the Same. For example, If you do this Driver Change in a Game that requires DXR it won't even boot and you get the same errors as you get on an rX 5000. Or in Games that have RT as an Option, they will grey Out. Regarding differences, whatever they are it is not "No RTGI and No reflections". They are very obviously there and multibounce etc. Just Like HWRT

Ray tracing is on in those comparison screen shots. They're talking about enabling the hardware accelerated path versus the software (I'm guessing compute?) path on the hardware (via driver settings). Not enabling/disabling ray tracing itself in the game.
So do I. When RT is disabled in the Inspector, the game still utilizes the same acceleration structure underneath, which can be visible in the water, for example. There are still models made of triangles with visually equal quality to HW RT, even for characters (which clearly indicates they are not SDFs). Therefore, they either implemented their own BVH, BVH builder, and traversal/intersectors in compute shaders, which is hard to justify for the somewhat dubious benefit of being able to run RT on outdated hardware that would never provide a good experience. The second possibility is that the driver's software layer kicks in and takes care of this, at least on NVIDIA hardware, when RT is disabled in Inspector (it would be nice to verify this by looking in the reflections on something like 5700 XT). Anyway, it's curious to see that the SW implementation on NVIDIA delivers performance comparable to that of AMD's HW implementation
You can test this theory yourself by just loading up a game that only works with RT or only has RT effects with HWRT.The second possibility is that the driver's software layer kicks in and takes care of this, at least on NVIDIA hardware, when RT is disabled in Inspector (it would be nice to verify this by looking in the reflections on something like 5700 XT).

Yes, DXR games don't work; I've tried. Though I've not tested all games, as far as I remember, the SWRT on NVIDIA only supported ray pipelines. Yet, it's super weird to me if they went for their own triangle RT implementation.
