(It is still early morning in Europe, the answer rate over here might be somewhat slow. )
I for one shy away from extra drivers. Windows has all the software on board to make all regular peripherals work, and most often the drivers supplied by the manufacturer only add clutter I don't really need.
So all my CH and Saitek stuff runs on regular Windows-supplied drivers, and as of yet I didn't have any issues with any simulator (DCS, ASF2/4, XP, Battle of Bodenplatte) or other game.
So: if every buttons and axis on your peripheral works, you might not need the extra driver.
