Daniel, I just encountered a similar problem running Carlson Survey with an embeded Intellicad 7.2 engine. In short, based on me calling Carlson, I entered the following command: "hwacceleration" and switched the default hardware acceleration value from ON, "1", to OFF "0" and degraded the graphic processing to bitmap (.bmp) vector graphics. Works fine, though I am not doing any on the 3d modeling the AutoCad products like Civil 3D or Revit could do.

I'd like to understand whether it is possible to do the following and the practical issues that may arise: - add a second video card/GPU to the machine - add a second monitor, connected to the new video card/GPU - associate the second video card/GPU with the guest using PCI passthrough Some questions come to mind: - how stable is the passthrough support these days? - how will the mouse pointer and keyboard know when to interact with the guest and how to get them back to the host? - how to install the video card driver in the guest, will it just work in a VESA mode the first time it starts up? - has anybody tried this particular solution with AutoCAD, was it worth the effort? - can anybody comment on which brand of card is most likely to work with passthrough, e.g. the NVIDIA Quadro cards perhaps?
