A tip for those who use Supervision in Cubase 12 and you are experiencing ASIO spiking.
Inside all individual meters of Supervision there’s a little button in the preference to either make the meters sample accurate or give you audio performance, make sure this light is on (blue) for audio performance and you will see a dramatic drop in you asio meter and potentially stop your ASIo meter spiking
This is indeed a great suggestion, and I promptly checked my Supervision settings. They were all set to “audio performance”, and I don’t remember ever changing it one way or another, so that just might be the default anyway.
I think the default is ‘audio’ but you can see for yourself how much difference switching to ‘sample’ makes on certain meters, so if you see your meters running super fine instead of refreshing slower that could be contributing to the spikes
