Hi All, I would like for windows 10 to display and update the graphics settings for my IMac. Thank You, Steve
Hi @steves15, Parallels Desktop is using hardware-assisted full hardware virtualization that relies on the Intel VT-x technology and allows simulating the whole computer with its hardware and software. This simulated environment is called a virtual machine. Parallels Desktop has no access to Mac's physical graphics cards. Instead, Parallels Display Adapter driver (which is part of Parallels Tools installation) interfaces with virtual hardware and provides 3D acceleration features. The actual acceleration is achieved by translating DirectX commands from guest OS to OpenGL API on macOS side. Most of Macs have an integrated graphics, which is built-in to motherboard and shares memory with the CPU, it provides a more economical alternative to the stand-alone card, known as "discrete graphics" or "dedicated graphics". In this case Parallels Desktop will use the resources of Mac's built-in graphics.
