The only thing your system would benefit from newer nVidia drivers would be security fixes in case of absolute 0,001% chance your GPU would be targeted by hackers. What about testing those games (? I don't know those you captured sorry) with the last ones your graphic card manufacturer put on the official website ? (Yeah it should be some crazy old drivers but you would know if it's about drivers).
