Noel,
thank you for extensive answer.
I did not had this issue before...this is fairly recent.

My system is a 6 core 2.8-3.5GHZ i7 with 32 gb ram, BIAB is on NVME SSD drive. It should fly. Nothing heavy is running on background. When using BIAB, resources do not even hit 18% mark under any circumstances (regenerating, VST etc.) Nothing seems to spike. That what bothers me.

As I mentioned, I have tried 2 audio cards with well written ASIO drivers, that do not give me trouble in any other software or media playback.

I do not believe it is a good idea to set MME for a dedicated ASIO card smile but for testing purposes I will consider it. Hopefully PG tech will get back to me about the crashes that I had, maybe that will shine a light on this latency/shuttering issue.

Thank you,
Misha.
