[/quote]That is changing, quite a few VM's support OpenGL (VirtualBox, maybe VMWare Workstation, Parallels) and some are supporting DirectX using Wine DLL's. [/quote] Yip, virtualbox OSE has support for opengl hardware acceleration and it even has a built in function to install wined3d :D I don't think it intercepts anything, it just replaces the directx DLL files which sends out opengl functions instead of direct3d functions. But actually I have no idea how it works ;)
