Any 3rd party SW to see what is driving C9 ASIO meter high?

Hi - I know Cubase doesn’t have any native functionality to tell us what is driving the ASIO meter (i.e., this plug in, or too many audio files, or too much VariAudio not yet rendered, etc.).

But does anyone know of a 3rd party program that might do that? I’m getting very high ASIO meter (F12) values, and slowdowns/audio problems lately. I thought that freezing VSTis, and bouncing most of the VariAudio bits would help, but not much. So I’m guessing it’s too many plugins.

Thanks for any suggestions!
