Hi, thanks very much for your reply.

I have gone through the Windows 10 optimization steps from the Avid KB, and from generic third-party search results.
The only other processes running during the PT session are background services, and wireless network / bluetgooth is disabled (wired ethernet is enabled).
The sessions are all audio, and limited to a multitimbral xpand track (plus click | delay | reverb).

I was hoping the issue would be specific to the full Pro Tools generic config, since it does not occur running PT | First.

AvidAppManHelper.exe starts and stops every few seconds, and often reports a crazy number of page faults.
I can't tell by watching if the delay occurs when it starts/stops, and i guess i could run procmon to see, but...wow.
Long road there.

Is AvidAppManHelper required ? I'd like to at least eliminate it as a possibility...if i can figure out how to safely disable it.

Thanks again, i appreciate your time and attention.
