I’m a super long Cubase user on PC and really never had that many issues, but.
I’ve been dealing with a GUI Freeze issue in Cubase 14 and 15. For example, I’ll have a session loaded and working, decide to pull up the “Frequency 2” plugin, the stock Cubase one, and it brings up the plugin, but won’t show the actual eq curves enabled. It will take about 10 minutes for Cubase to again become responsive and some cases not at all. I then have to end task and restart. This has happened when duplicating a track, opening the Audio Connections window, disabling or enabling tracks etc
Basic Facts::::::::::::::::::::::::
Windows 11
NVidia GPU
Cubase Pro 15
UAD audio driver (all latest updates)
When this happens, I can open a web browser and other programs with no issues and the computer is very responsive, just not Cubase itself. Which makes me think it’s not hardware. My CPU is around 5% with 40GB ram left free, GPU seems to be running low 7%ish, all hard drives are very low 1-5%.
I have tried:::::::::::::::::::::::
-Different GPU Studio stable drivers for my NVidia GPU
-clearing the GPU Open GL Cache
-Deleting and reinstalling all my plugins.
-Moved all of my VSTs out of the VST folder and then 1 by 1 tested them,
but was unable to zero in on one plugin.
-Deleting Cubase preferences.
It does seem to go away in safe mode. Which led me to think third party plugins,
but Cubase stock plugins are the ones I interact with before the GUI Freeze occurs.
Because Cubase is not actually crashing, I don’t know a way to get a crash report.
To get more information. Does anyone have any ideas? Willing to revisit anything if it will fix it.
I’ve got a similar issue. Not to the extend that I have to use taskmanager, but I have also noticed some kind of micro stutters in the cubase gui. Mostly when opening and closing plugins (stock and 3rd party), but also while doing nothing and cubase just “idles” the GUI laggs for a couple of seconds then goes back to normal.
Interestingly only the GUI seems to be affected, as the audio playback continues smoothly in the background.
That is actually on purpose. GUI threads run with a much lower priority as DSP/audio threads, so that in case of CPU contention the audio will run as long as possible without dropouts. A good sign for this scenario would be e.g. if the meter’s don’t get updated often, or the song cursor jumps.
In the cases described here, it seems a bit weird, unless your CPUs are actually saturated, the GUI should’t really stutter or lag. opening plugin windows can take some time, depending on the plugin.
It is difficult to diagnose remotely, but apart from trying the old “safe mode with disabled preferences trick”, I would try to create a new empty project, with just an audio track, then see whether your problems also occur. If yes, there is most likely a general issue with your computer or setup.
If not, try adding more tracks, then Cubase internal plugins, then maybe your most used third party plugins. Also, check if there is a difference when tracks are record/monitor enabled or not.
Okay after pulling several crash dumps, they all reveal the same suspected issue. For some reason on Windows 11, with Cubase Pro 15, “Berlin Studio Reverb” continually causes this GUI freeze issue. There are several failures listed in the crash dumps. It happens when I do several different things in Cubase:
-Importing a track with an instance of “Berlin Studio Reverb”
-Adding a new instance of “Berlin Studio Reverb”
-Opening the GUI window for Soothe 2, oddly
-And many others
Without the plugin in the VST folder, I have no issues. I have the latest version of the plugin and have emailed the dev a few times. For now, I have switched to another placement reverb. I’ve since worked many hours with these changes, so it seems this is the issue. Thank you for the replies! I know understand how to troubleshoot GUI freeze issues.
