When I had a GTX 750 Ti I remember being able to update it from the Nvidia Shadow Play panel. I never had to go and download a driver to install. It would tell me when there was an new updated driver which was like every time a new game came out and it was annoying as hell. I was seriously updating the driver like every few weeks or so. I also did a clean install each time meaning the NVidia software would remove the old driver and install the new one.
