Leo,

39% CPU load is extremely high, especially for your setup.

To help you track down, can you repeat all of the steps again but don't try the Pianoteq VSTi and see if the CPU load is more normal?

Running the same VSTi on 4 tracks is likely to be problematic. The same VSTi code is trying to compete with delivering to 4 tracks simultaneously.

As mentioned previously, others are not having issues such as yours.
