Hi, I had same issue. Resolved!
After looooooong investigation, I remembered that I had modified my win10 system, long time ago, it was in order to make Halo infinite work.
So I reversed what I had done and bingo this command below worked for me :
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V
I have 3060Ti and Ryzen 5600X (using only 3cores and 6threads). Now I pass the Cyberpunk benchmark @60fps, before the command I was @19fps with GPU under-working (30% refering to msi-afterburner).
This behaviour is odd because Halo worked fine and even 3dMark gave me good results with Supervisor activated. Is it a Cyberpunk bug? Maybe a feature..
