i use windows 10 cause its better for new machines like Ryzen 5 1600...
my Asio buffer is at 64 samples with minimum latency selected from the option menu of Audient id4
if you have a strong pc then latency isnt a problem with this interface.
i use guitar sims and i worry about latency too.
Reaper reports 2.4/2.4 asio which is a good latency for amp simulator.
