New Graphic Cards are supporting the new Direct X version. To have the performace you expect when buying a new Graphic card is not that big if the game codec is running on an older Direct X version.I Upgraded from NVidia 960 to a NVidia 1070. Some effects have been added but not as much as expected. Compared to a Game that have been coded for Direct X 11/12 the imporve after this upgrade was not as expected. Maybe this will bring back more players to GW2 if the game is beeing moved to an actual Direct X version that will use and support today features of newer graphic Cards.
