 The NVIDIA driver is software that allows the operating system to communicate with the NVIDIA graphics card in order to control the GPU, manage performance, handle displays, and run graphics smoothly. This enables the computer to properly use the GPU for things like fast graphics, gaming, video editing, and hardware-accelerated apps.
