If you play games that place heavy demands on your system, it is a good idea to regularly update the graphics drivers for the best performance. That’s a job you don’t have to worry about because both AMD and Nvidia offer programs that replace the old driver with the new one with one click. However, over time it can happen that remnants remain that lead to problems with games. In that case, you can completely uninstall drivers with Display Driver Uninstaller and then do a fresh install. Read the instructions carefully!
