Problem with my Graphic drivers version

Hi,

   Recently I was told to update my Intel HD Graphics driver, so I updated it to version (8.15.10.2993).

   Problem is after installing the latest driver version, my system rating for Graphics came down to 4.8 earlier it was 4.9. does this will effect my gaming performance?

   (Note:- Gaming graphics rating stayed same for this new version also i.e 5.3)
