Thanks but 1) done, 2) done, 4) ryzen 7 no lack of cpu power
This issue has nothing to do with ASIO buffer - even with a low ASIO buffer I have a crazy latency in some projects.
1) Sonar is missing a plugin performance summary - there is no way to identify culprits
2) Something could be better in the PDC processing. Same setup/plugins in Studio One give me super low latency - in Sonar it is like the latency cumulates through all the channels. I think the cause might be compressors with PDC on all channels (again no way to check) but the way the PDC builds it chain, channels are not running in parallel...
