The NVIDIA RIVA 128 is an older graphics card that was part of NVIDIA's first-generation GPU series, originally released in the late 1990s. It was marketed as a low-cost, high-performance solution for gaming and multimedia applications, designed to deliver 3D graphics acceleration at an affordable price. The RIVA 128 used the NV4 chip and offered features such as hardware acceleration for 3D graphics, video playback, and 2D rendering.

The NVIDIA RIVA 128 Windows driver is the software that allows the operating system (such as Windows) to communicate with the RIVA 128 hardware. Drivers are essential to ensure that the hardware functions correctly, enabling features like display rendering, video output, and 3D acceleration.
