As someone who uses an Igpu for day to day life, but occasionally some games. It is unacceptable that the newest drivers available are just under A YEAR OLD. When I consider the fact that I know that intel released newer drivers several months ago that vastly improve the performance when it comes to a game a play, it is very unfortunate.
I'm not suggest that every intel drivers need Dell validation ASAP, but for GPU's please try to do them in a timely manner.
FYI I have an 2013 (Haswell) XPS 13
