I am currently attempting to set up a Ubuntu 21.04 Virtual Machine on Virtual Box and am attempting to use the 3D acceleration and it is refusing to use the Nvidia GPU and instead uses the integrated graphics card instead.

Host Setup:

Windows 10 x64

Nvidia GTX 1660Ti

I have specified the graphics card to the High-Performance NVIDIA Processor in the Nvidia Control Panel for the following

C:\Program Files\oracle\VirtualBox\VirtualBox.exe
C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe
C:\Program Files\oracle\VirtualBox\VirtualBoxVM.exe

I have also installed VirtualBox Guest Additions and have checked using nux that 3D acceleration is working

Not software rendered:    yes

Not blacklisted:          yes


GLX fbconfig:             yes


GLX texture from pixmap:  yes


GL npot or rect textures: yes


GL vertex program:        yes


GL fragment program:      yes


GL vertex buffer object:  yes


GL framebuffer object:    yes


GL version is 1.4+:       yes


Unity 3D supported:       yes

Therefore 3D acceleration is working but seems to only be using the intel one.

As far as I know, you can't pass a PCIe card to VirtualBox from a Windows Host. It is possible from a Linux Host, or Xenserver, and even then you need to have the correct hardware in other to do so. The CPU hypervisor need to be enabled for example.

At best with a Windows host you can get more video ram(up to 128mb is I remember right)once you dealt with the VirtualBox Guest Additions

I went though this once, so I dig up some of the reading I did
