DLSS and Raytracing

Is there any kind of Documentation or so what is the correct way on Bottles to enable Raytracing and DLSS? I found much contradicting information, which of DXVK_ENABLE_NVAPI, WINE_HIDE_NVIDIA_GPU, PROTON_HIDE_NVIDIA_GPU, PROTON_ENABLE_NVAPI, VKD3D_CONFIG is actually needed, and which cause problems or do nothing at all. From what I understand, manually copying files or creating a dxvk.conf is no longer required, but again, I am not sure about that.

I did a few tests myself, some games work with DLSS and some dont, and I think Raytracing requires VKD3D_CONFIG=dxr.

But I really would like to know the official and “best practice” way to enable both DLSS and Raytracing that works consistently on all games that are supported.

Just out of curiosity, will Bottles next support DLSS and Raytracing out of the box without having to set env vars manually, or will that still be required?
