Hello Petera2, Guest OSes in Parallels Desktop have no access to physical graphics cards present in a Mac. Instead, Parallels Display Adapter driver (which is part of Parallels Tools installation) interfaces with virtual hardware and provides 3D acceleration feature.Please refer to http://kb.parallels.com/122807 to learn more.
