Cubase 12.0.30 performance issues

Video playback is choppy when the window is scaled up, whereas it was fine using Cubase 10.5. (it was the same with 12.0.20)

It’s unusable for ADR the way it stands now. Is there some new setting I’m missing after upgrading?

Mid 2014 MacBook Pro SSD maxed ram
Big Sur 11.6.7
Cubase 12.0.30

So, my W10, i7 7700, 16G of ram, updated W and a stable running C11 setup does not like C12.00.30. Even after just one VST (BX_Oberhausen) it peaks and therefore it clicks with the peaks. I really want to use this version because of midi integration! Is there somewhere a place where solutions are mentioned as a list in stead of everywhere in losts of text? I already disabled my hyperthreading (didn’t do it).

Does this mean that Cubase is not at all to blame for the problems described in this forum?

Very unlikely.
However I am on Win11 and don’t have any of the above mentioned problems.

This afternoon I got another one of those issues I’d described above:

where there was a hang in Cubase 12.0.30, so it had to be killed, and trying to start it up again results in Cubase disappearing pretty quickly without a DMP file but putting an exception code 0xc0000374 in ntdll.dll from within Cubase in the Windows 10 Event Viewer as follows:

Faulting application name: Cubase12.exe, version:, time stamp: 0x6294f7ac

This time prior to the hang, I’d backed up a project to a clean directory (using the Project/Backup Project facility). After doing that, I’d wanted to close the original project then load the new backup version to do a sanity check on it, but Cubase wouldn’t even make the project close button active. I let it sit for on the order of a half an hour after that before trying again, hoping maybe it was just delayed, but no go. I made a procdump dump of it to look at afterward, but I also noticed there was a freezedump file in the CrashLogs directory from somewhere around the time the backup operation would have been running or completed, and looking at both DMP files in Windbg preview shows the same location and stack track. Here is the one from the freezedump file:

I’ve tried multiple times restarting Cubase, but no go, so it looks like I’ll need to reboot (which did clear the issue last time). I’ll let Cubase send the freezedump file to Steinberg when I can start it again.

It may be worth noting that, prior to running the backup operation in the project, I’d made all tracks visible and enabled tracks that had been disabled (because I wanted them to be included in the backup, but I did not want other audio that is no longer used in the project included in the backup – this is for making an archive of a project I recently finished, and I will disable the tracks that had previously been disabled once I can open the backup project in Cubase again). I did not actually play the project or do any editing during the Cubase session.
