Using externally Mounted GPU for Display Driver in Windows

[petera2]

I have an NVIDIA GeForce Titan GPU mounted via thunderbolt on my Mac
In my Parallels Running Windows 10
Under
Settings: Device Manager: Display adapters: It shows
Parallels Display Adapter (WDDM)

Is there a way I can point that at the external GPU card.

that way I can GPU render from within Windows using GPU Rendering software

Many thanks

Peter

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 features. The actual acceleration is achieved by translating DirectX commands from the guest to OpenGL API on OS X side, please refer to the link to learn more.
