Clan mate who runs a R7-3700X and 2080 suddenly got the same problem yesterday, had no problem until then. Only change was his nV drivers updated. Rolled back the drivers, same problem. Something must have broken D2 that it can’t recover from. He’s currently wiping his PC and taking a day to redownload D2 (slow internet). There doesn’t seem to be any rhyme or reason to crappy performance or not. I played 6 hours last night (few runs of Harbinger and other stuff) and had zero issues all evening, logged in this morning to do Tower stuff and it’s a slideshow. Takes 2 seconds to draw the character boxes on the login screen...
