The default max video memory in VirtualBox is 250mb, this is not enough to run graphic dependent applications in the 'Guest' (like a CAD program)
I think I seen something somewhere about GPU Passthrough? Could not find anything about it in the FAQ. Is Passthrough possible? and if so how? Thanks

Re: Using host GPU
Assuming you enable 3D acceleration then graphics are rendered on the host. All the guest needs is a buffer, and 256MB is plenty.
