Hey all,
Maybe dummy question but I am curious about this.
I recently upgraded from AM4 platform to AM5 e.g 5800X to 9800X3D. And as you most likely probably know the 9800X3D already does have an iGPU. Thus this is making having my system a dual GPU setup.
My question is, in such cases there is a “prime” which controls what GPU should be used ,cause I read that by default Garuda uses the iGPU. However this doesn’t seem to be the case now, when I check nvidia-smi or the KDE monitor, I see that the External GPU is used without any additional tinkering.
Is this a normal behaviour? Did something change or what kind of voodoo is this?
I am asking cause I am not sure if I should still setup prime. Or if it can down the line without prime cause some issues.
