Ok i have a really BAD problem, i was playing the game really well load of 3seconds or less and no problem running high graphics, then i updated Nvidia driver and games goes to hell, serius fps lost every time i check an item on inventory or open my equip tab, then lost hella lot of fps on the golden chest selecion phase on nest and dungeon, heck i lose 3 chest cause of the fps drops, the problem is only on DN since i play dota, halo, and other games and have no problems there, i think DN got some setting or is not updating up to date graphics, plz help i seriusly cant play with that fps drop and btw now i neecd like 20-40 second loading screens from 3 seconds
Using:
NVIDIA GeForce GTX 1060 6gb
16gb ram ddr4 3000mhz

game is on an SSD drive

Game was running ultra fast before Nvidia update (and yes is the update i have tested it) i downgrade my graphic one time and games go back to normal but after this NVIDIA update i no longer can downgrade the graphics again so i m stuck and can't play the game with that many fps lose, plz help
