Ahhh.. thanks for this clarification.

I'm not sure where I read that full virtualization provides direct
hardware access mediated via the Hyperviser, but I thank you for forcing
me to research this a little further.

So really, if you want 3D acceleration for games, there is no VM
solution that will cut it at this point. I guess that about sums it up?

I could have sworn that one of the VM makers included some direct
hardware support. Looking into this further, VMWare offers some
experimental DirectX accel, and a forum post says that Virtual PC does
too. I guess that's what Mark meant by this pushing the envelope

Oh well, the game that I wanted to run (Civ IV) does seem to work in Wine:

What kind of performance hit can one expect with Wine these days?
