3Dfx Interactive Inc. was a pioneering company in the graphics hardware industry, best known for its Voodoo series of 3D accelerator graphics cards. These cards were popular in the late 1990s and early 2000s for providing hardware-accelerated 3D graphics in video games and applications.

The 3Dfx Voodoo drivers are software components that allow these graphics cards to function properly within the Windows operating system. These drivers enable the GPU (graphics processing unit) to communicate with the operating system and applications, providing enhanced graphical performance and effects for games and other 3D applications.
