For those considering upgrading to windows 10, I have personaly tried every build up to and including build 10130, although it is working on all versions, I have found that build 10122 and 10130 are the only ones which play navyfield without any issues.
Issues I have come accross are, in game graphics lag (not server lag), screen freeze, lock up on win result screen, constant reloading of graphics in game rooms and various others.
I hope this helps others considering the change as I have spent nearly two weeks trying this.
So in conclusion my system works best with windows 10 build 10130, if anyone else has tried windows 10 please let us know your results.
