I’ve been battling the long load times since launch with a 4090/7950x3D/128GB DDR5 setup and a gigabit connection. Tried everything listed with no luck and ended up being an outdated AMD Adrenalin CPU driver causing the issue. My load times went from 45 minutes to an hour consistently down to sub 3 minutes. Anyone running AMD check your drivers and update if you’re having issues, maybe it’ll help.
