Directx on a windows 7 guest

Postby buscon » 9. Jul 2013, 14:36

Hi,

I have installed a virtualbox on a macbook with a windows 7 guest.

Now I need to use the graphic card with directx drivers but the graphic card is recognized as virtualbox graphic card.
I don't need 3d features, I just need that the video card is recognized by the directx drivers.

How can I do that?

Best

You can't. Virtual Machine == a simulation of a PC, not a real PC.

If you turn on 2D or 3D acceleration then some features of the host graphics will become available. However the guest will never see the host hardware directly.

No, the guest will see DirectX drivers - provided you install and enable the appropriate VM features, it just won't see any hardware that doesn't belong to it.

ok, good to know, but how can let my windows see the Direct X drivers?
what do you mean "install and enable the appropriate VM features"?

I have installed the host extensions without the experimental 3d feature.
What else should I do?

You need to enable the 3D feature and reinstall the Guest Additions. See the user manual for a detailed howto. Pay particular attention to the difference between the basic and experimental WDDM drivers (the former needs to be installed in safe mode, the latter doesn't). The GAs provide DirectX APIs.

Solved by changing graphics controller setting from VBOXSVGA to VMSVGA and enabling 3D acceleration.
Hope it helps :wink:

I'm afraid that neither of those options existed in 2013.

I'll lock this topic to prevent the dead being disturbed further.
