Further tests improved the performance of the 10940x even more. I found out that Win10 was set on balanced energy mode, once I set it to the max setting, it runs like a charm. Instead of 6 heavy processed audio tracks, I am able to run 15 in the project and asio buffer runs totally smooth even on 64 samples buffer size. This shows that you can gain so much more performance tweaking the settings. Finally I don’t regret the pc update anymore.
