VirtualBox 的 3D加速只有條件的支援OpenGL
4.8. Hardware 3D acceleration (OpenGL)
Starting with version 2.1, the VirtualBox Guest Additions for Windows contain experimental hardware 3D support.
With this new feature, if an application inside your Windows guest uses 3D features through the OpenGL programming interfaces, these will not be emulated in software (which is slow), but instead VirtualBox will attempt to use your host's 3D hardware. This works for all supported host platforms (Windows, Mac, Linux, Solaris), provided that your host operating system can make use of your accelerated 3D hardware in the first place.
The 3D acceleration currently has the following limitations:
1.It is only available in Windows XP and 32-bit Vista guests with the Windows Guest Additions installed.
2.Only OpenGL acceleration is presently available in those guests; Direct3D is not yet supported and will be added in a future release.
3.Because the feature is experimental at this time, it is disabled by default and must be manually enabled in the VM settings (see Section 3.7.1, “General settings”).
