The Voodoo2 3D Accelerator is a graphics card developed by 3dfx Interactive in the late 1990s, known for its revolutionary 3D gaming performance at the time. It was one of the first graphics cards designed to handle 3D rendering, and it became highly popular among gamers. The Voodoo2 accelerated 3D graphics for games, offering smoother graphics, better textures, and more complex effects than the software-rendered graphics that were common at the time.

The Voodoo2 Windows driver is software that allows the operating system (typically Windows 95, 98, or ME) to recognize and properly use the Voodoo2 graphics card for hardware acceleration, including 3D rendering for video games and other 3D applications.
