I have Apple MacBook Pro Retina display with NVIDIA GeForce GT 750M I installed Microsoft Windows 8.1 Pro with success, however windows does not recognize that I have nvidia installed in my system. My question is: How to let Parallels Desktop 9 to enable NVIDIA to be installed in windows 8.1 pro? If it does not support it, what other tools or software to make nvidia work in windows 8.1 pro? Thank you.
