Enable IPV6 in network settings. In game. or at character selection screen in the menu.
haven’t played in 2 months, rebuilt my PC(overkill build for this game) and came back to oddly large load times. both when loading game and when hearthing or using portal. re-enabled ipv6 (remembered this from a long time ago.) and load times are back to non-existent.
Cheers if it help.
