Good to hear it's resolved.

Could you explain a bit more about what you mean here.

For serious volume rendering you really need an NVidia or AMD
dedicated graphics card.  This has more to do with raw performance for
doing 3D volume rendering than compatibility.  Intel drivers can be a
separate issue, as can be support for 3D textures.
