AMD RDNA 2 GPUs to Support the DirectX 12 Ultimate API

[bug]

I remember reading an article that NV did RT for RTX different from DXR and Vulkan RT.

If it's just a matter of relabeling calls I suspect there will be no difference or superbly minimal difference.

Then again I was around for the FX series, so I'm interested in seeing some benches.

There are usually some vendor specific extensions around, but you don't have to worry about those. They either make it into future DX/OpenGL/Vulkan versions, or they just slip into irrelevance.
