I had a hard time configuring my setup at the beginning to reach good latency and although I used DPC Latency too, it never really helped me. It just shows latency peaks you may have but it doesn't tell you what to do. or did I miss something?
It works in micro seconds or x.xxx1 and I know for my MK2 console it works in sec x.1. My peak was around 4,000 micro seconds so I set it at 4 seconds for example. You can also set it higher to play it safe.
When I mix 2 songs I set it at 4 sec and when I do a set I set it at 6 because for some reason after an hour or so it's not as responsive for a while then it fixes itself.
Don't know if this is any help but this is what I found from tinkering with it and doing a little research.
