I have this on both my previously fine 14Pro and also 15Pro now. I did update to the latest version of 14 yesterday.
Since then, on playback and during general editing there seems to be a pause every second or so. It is extremely distracting as you can imagine.
The audio still runs as it should but watching the timeline it pauses every second or so as described.
Never had this issue till yesterday and my system is pretty decent - Mac M2 Studio with 64GB RAM and Yamaha DM3 desk/interface. OS is now Tahoe but as said until upgrading yesterday C14 ran like a dream.
This is with one drum track and a synth, so not exactly overloading the system.
As you describe it (so it affects both your Cubase versions), it sounds like any global component has been updated. This could be HALion Sonic, or EuCon, for example. Anything you can find in Library > Application Support > Steinberg > Components.
Ok, with very quick help from Steinberg Support, the issue seems to be my Templates had open Inspector and Mixer desk windows open behind the main screen.
This can cause this issue and closing the hidden items fixes this. Have saved my Templates without extra hidden windows and all is good.
It will be fixed down the line I am told.
Thank you Martin and Steinberg for hopping on to this one.
I played around with it and the stutter always comes back as soon as you have a window open, e.g. like channel settings per instrument or a separate mixer window. But only if it is covered by the timeline window! Guess I have to make sure my timeline window never covers anything - at least till there’s a software fix
I’m getting this with both Cubase 13 and Cubase 15. I first noticed it a few days ago before Cubase 15 released. Coincidentally the same day I updated to Tahoe 26.1 ?
So I think it’s possibly related to the Tahoe update more than the Cubase 14/15 updates as it’s also newly present in 13 for me which I haven’t updated in about 6 months?
Thanks to @dreikelvin disable GPU acceleration works for me in both 13 and 15
Don’t know about stuttering, but I’ve observed a considerable delay between using a keyboard shortcut for the 1st time, and consecutive uses. To the point that I wasn’t sure the key press has been registered or not. I need to pay more attention to it.
It’s weird, because this wasn’t happening in 14 not in 15 beta.
Usually I test everything on my laptop before I install it on my main station - but this time the issue was so hidden, I did not notice it first - most often I just launch Cubase/Nuendo and then just load an old project. In addition, if I do something in the channel window, I always close everything before going elsewhere because of that limited screen estate. So that stutter effect occuring is less probable on a laptop.
This is different on my main computer with a 50" screen with multiple windows open.
Funny thing btw, the stutter is a lot “smoother” on M4 (and probably even less noticeable on M5) because how insanely fast these CPU’s are lol
Just got info from support that a maintenance update 15.0.10 is on the way. No clear release date yet.
And no info if they will release an update for Nuendo 14. N15 is around the corner so I am crossing fingers when it’s out, it will be already the patched version.
