NVIDIA GeForce Driver is a free update, provided by NVIDIA, to the base software that powers your graphics card. At least, assuming your graphics card was made by NVIDIA. In particular, if your computer contains one of the older GTX 400, 500 or 600 series GPUs, you'll have much faster speeds in all but the most modern games.

Kick Your FPS Up A Notch

The latest NVIDIA GeForce Driver provides up to 50% faster speeds in certain games on certain graphics cards. The actual improvement varies based on what graphics card you have, and the latest graphics cards, such as the GTX 1050, running the latest games, such as Dark Souls 3, may not see a pronounced difference in speed after updating your drivers. It's still useful to do, though, as every little bit helps. Still, power users may see some use in the latest NVidia GeForce Driver, as it provides additional SLI profiles for certain games which otherwise may not take advantage of two or more graphics cards.

Keep It Up

Overall, there's no harm to updating to the latest NVidia GeForce Driver. Even if your graphics card is old – in this case, especially if it is old – it's wise to keep your driver for it updated to the latest version. Between modest speed increases for older GPUs, and SLI profiles for the most powerful machines to make use of, this is a solid update.
