These tasks are all done pretty much automatically. That is, the program will automatically detect any updates, and you just press confirm to download and install the drivers.
In addition, from the control panel in GeForce Experience, you can optimize the performance of all the games you have installed (even if they have been installed through Steam). The application recognizes games like Tomb Raider, Fallout: New Vegas, Battlefield 3 or The Elder Scrolls V: Skyrim. And it will not only recognize them, but also set the best possible graphics configuration.
GeForce Experience is a very useful tool for any user with a NVidia graphics card and will save them a lot of problems. They will also get more out of some video games whose performance is greatly enhanced depending on the drivers that are installed.
