Hi,
ooouuuhhhh...now things are becoming really weird...:
After reading your post (thanks for the indepth analysis!!!)m I set this:
>=x11-drivers/nvidia-drivers-396.24-r2 X static-libs uvm compat driver acpi
>multilib
and got this:

...multilib is ignored....
...because I am on a 64bit-only system???
By the way: For testing purposes, I installed the nvidia-drivers as
they are provided by nvidia and can activate Optix in blender then.
I prefer the "Gentoo-way", though.
Hmmmm...
And: ABI_X86="64 -32 -x32" does not include "amd64" but only "64"...
Cheers!
