If you are picking up Fallout 4, Starcraft II: Legacy of the Void or Starwars Battlefront and have a NVidia card on your PC I recommend you update your drivers. NVidia has released a special game ready driver to help things out with the launch of these games. You don't want to explore Boston or fight Nerud as the Protoss with graphical glitches and performance woes due to drive issues.
