I can say that I didn't have latency problems or any problems for that matter using Cakewalk with 3900X (Asus Prime X570-P, 64Gb 3666-16-16-16 ), everything worked just fine. Ryzen systems may need some fine tuning, thats all. Now I got 5950X, which maxes at 5075 GHz and have even less problems ;-)
Anyway, the difference in performance between Zen2 and Zen3 is really mindblowing, that's for sure.
