GPU not showing

I read many similar post about this topic, but after trying many of their propositions, I fail to succeed. Please help because I’m a bit desperate as I’m not using the whole potential of my pc.

CPU:AMD Ryzen 9 5900X 12-Core Processor 3.70 GHz
GPU: AMD Sapphire Radeon RX 6900 XT 16GB
RAM: 32,0 GB
All drivers updated.

For some reason, CUDA is empty and in Vray assets Cuda options only show up the CPU:

OpenCl comes with two GPU that are the same:

Vray assets - CUDA only showing CPU:

RTX empty:

AMD Software: Adrenaline Edition

CUDA is Nvidia-specific.
(see Is it possible to run CUDA on AMD GPUs? - Stack Overflow)

If V-ray doesn’t support OpenCL or whatever AMD uses, it quite likely won’t be able to use your GPU.

Um yeah? Yes it is hard to believe…

This isn’t even a Rhino issue why are you asking here, is Chaosgroup support that bad?
