I have now played to over turn 900 on the giant map after the latest Civ 6 update. You will still have to choose your mods carefully as the asset limit will still cause crashes if you do not limit the number of mods you are using. Also, for some reason Warfare Expanded Unloaded will not let the game load but you can used Warfare Expanded Complete version. Be aware that this mod sucks up lots of assets so limit your other mods or you will get a crash when "X" amount of units exist on map. I also disable Sea level rise and coastal flooding when using this map. I am glad FIreaxis finally gave some love to larger maps as this is my favorite. As a note, I also only use old world civs on this map to limit asset overload.
