I had been having what I thought was good performance in windows 10 with
4970K Asus Z97I + RME UFX
Cubase 9
If my project had a good number of plugins , (mostly a waves user)
My ASIO meter would start to spike randomly after it reached about 75%.
So I would just start rendering and freezing tracks where I could.
I just updated the firmware on the RME UFX …
It was less than a year ago I had done it previously .
Great improvement with the new firmware,
ASIO meter is smooth all the way to 100% no random spikes
Very roughly 50% better performance.
Hope this can help someone.
NB
