Following its announcement last week, Parallels Desktop 3.0 for Mac has shipped, introducing 3D graohics support.

Parallels Desktop 3.0 allows a Mac desktop user to run Windows, Linux or other operating systems alongside Mac OS X.

By supporting the OpenGL and DirectX graphics libraries, version 3.0 makes popular Windows 3D applications available to Mac users, including graphics-intensive games. It can also run Windows-based 3D computer-aided design programs. Parallels hadn't supported 3D graphics previously.

Among the 50 or more improvements in 3.0 is "SmartSelect," which lets people use OS X or Windows applications to open any file type, regardless of whether that file is on the Mac or Windows desktop.

The upgrade also includes an improved security feature that takes a virtual snapshot of the computer's memory, hard disk drive and various settings to revert back to in the event of a system malfunction. It's also useful for installing temporary beta versions of new software, Parallels said.

Virtualization industry leader VMware is introducing a product that also enables running Windows on a Mac. VMware said it will be releasing the latest beta version of its VMware Fusion on Friday and will provide details on availability and pricing next week.
