Hi,
There is no pass-through of the graphics card to the VM.
The VM only sees virtualized hardware. It never gets direct access to your graphics adapter, instead it sees a virtualized graphics card that then renders on the hardware GPU.
For a more detailed explanation on how this works see this document: https://communities.vmware.com/t5/VMware-Fusion-Documents/Frequently-Asked-Questions-about-VMware-Fu... near the bottom at the "Virtual Hardware" section.
