[-- Attachment #1 --] Hello Stephan, A year a go I did try passtrhu a dedicated nvidia GTX 1650 while using integrated intel graphics (laptop Lenovo Legion 5 15IMH05). Windows detected card but nvidia drivers install failed at some point. On this laptop I did setup bios to use integrated graphics so I can passthru dedicated nvidia. Think I will give a new try since I follow main. Are you using laptops for this usecase? Thanks!
