AFAIK, for the setup they're talking about, you do need a dedicated GPU. You blacklist it on the host, and pass it through to the windows VM. I haven't worked in windows space in awhile though, and state changes rapidly, so there may be other options now that utilize a single GPU across host and vm without losing performance.
