Hi TheLoneVM,
This is the old classic version of Baldur's Gate II; I bought it in a pack of classic D&D games (BG I & II, Icewind Dale I & II, Planetscape Torment, Temple of Elemental Evil) about a year ago. Great stuff to play on a Windows netbook, and I was hoping to transfer them to my Mac, but it looks like VMWare Fusion doesn't play nicely with them.
There is only one choice for 3D Acceleration, which is OpenGL. From the README, I think the version is 2.5.26461 . It includes Throne of Bhaal, so it's at least at that patch level.
