I can’t say for sure, but since the last update, when I play my compositions, when I position myself on a Halion Sonic track, the peak performance saturates … if in the second that follows, while letting the piece play, I position myself on the master, everything becomes correct again … Strange, isn’t it? an idea ? Thanks the musicians
Je ne peux pas l’affirmer, mais depuis la dernière mise à jour, lorsque je fais jouer mes compositions, que je me positionne sur une piste Halion Sonic, le peak performance sature … si dans la seconde qui suit, tout en laissant jouer le morceau, je me positionne sur le master, tout redevient correct … Etrange non ? une idée ?
Hi,
Once you select the track, the Record becomes enabled automatically (thanks to the default Preferences setting). That means the track switches to the real-time (no ASIO-Guard anymore). Therefore it needs much more CPU power. At the switch moment it’s really a “shock”, later all becomes stabilised.

Thank you for your input 
Ok, but why now?
although I have been using Cubase for years.
Here are jpegs to compare
But actually, disabling the record (default) is ok… Thanks for the scoop
