This is an interesting development to say the least. I’ve heard rumblings that that other Mac virtualisation company, Paralells, was working on a similar technology, but vmware beat them to the punch.
The technology in question is basically a wrapper, where the vmware 3D driver captures DirectX instructions, and translates that to OpenGL instructions the graphical 3D framework in Mac OS X can understand.
I can see how that still reduces the quality and speed of gaming somewhat, but it’s still a milestone of no small proportions.
As for the future, I can see a sort of hybrid directx/opengl driver for Mac OS X, where vmware (or paralells) acts as a bridge, and sends DirectX codes directly to the OS X driver, which then performs the proper graphical mayhem without interference of the OS itself. Less software, more hardware virtualisation so to speak. But before such feats become fact, we’ll have a ways to go, and this solution offers, at least temporary, potential.
