3D Stager still dont recognize my GTXY 3080?

Seriously... 3D Stager hides the GPU render function as soon as I install a current driver. I have tried everything after a fresh reinstall of Windows 11.

> Nvidia Control > Stager 3D > high performance
> Windows 11: Graphics > Settings > Stager 3D > High Performance

> i installed nearly all studio drivers (ofc. firstly the suggested drivers)

I have an AMD Radeon 5900HX + a GTX 3080, even in Stager the GTX is shown but the GPU rendering is grayed out... see screenshot.

Rendering with my CPU takes on average ~5x longer than with the GPU, that can't be real... Adobe charges another 30€ more for the 3D Suite subscription and it doesn't work correctly. 

Adobe pretends that GPU rendering is a nice side issue, but it is extremely important! It saves a massive amount of time. If the 3D stager is to be competitive, something should change.
