Drivers control hardware and give software a simplified general way to use the hardware. You Know how your hard drive is full of files, it’s because you have a filesystem driver, which allows software (like games and other stuff) to access certain places on the drive without knowing exactly how to fetch it from the drive.

You don’t *need* to update the drivers, but graphics cards are pretty complicated and so are heir drivers and the driver developers frequently figure out better ways to use the hardware. Graphics card drivers are often a collection of drivers for lots of different cards so updates may bring along a new driver for a new card.
