i9-13900K & RTX 3090 working together, but only i9-13900K detected

Hi Charles:
I am working with your gpuR library; I have installed now both i9-13900K and RTX 3090 GPU in my setup; gpuR library detects both, but when I run currentDevice() function, only i9-13900K is detected What am I doing wrong??
Both, intel OpenGL library and ncOpenGL libraries are installed.
Thank you very much in advance for your support.
Fernando.
