Graphics driver or video driver play an important role in Windows performance. Out-dated or incompatible graphics drivers are one of primary reasons for BSOD (Blue Screen of Death) errors. Although updating Graphics card driver, also known as video card or GPU driver, generally doesn’t improve the system speed, having most recent graphics or video driver will surely make graphics intensive jobs much faster.
NVIDIA, AMD, and Intel graphics generally release updates to graphics drivers multiple times in a year. Although there are official tools available to automatically update graphics drivers, these graphics card manufacturers don’t offer official tools to completely uninstall graphics driver, if required.
