Cubase 14 Macbook M1 Pro CPU Usaage

Recently updated to Cubase 14.0.10 Nov 2024 build. Now have very high resting CPU usage even when idle and massive spikes running even a few AU plugins.

All plugs are silicon ready (one is NI Kontakt, sigh) and Machine is MBP M1 Pro running Ventura 13.6.9.

My SSL UF8 and UFC have also started triggering notes on virtual instruments which is also annoying.

Anyone have any ideas I have reinstalled Cubase Pro but still have the same problem.

I’m having the exact same issue on a Mac Studio. Incredibly frustrating.

That’s interesting because I was thinking about getting a refurbished Mac Studio because I needed more power.

Steinberg - any ideas or do we all just make other arrangements?

Everything was working like a dream. Then something happened and I have no idea what. :weary:

Cubase 14 happened.

Just opened the C14 test template with 6 VI’s in C13 and the CPU Usage barely registers so, on my machine, there is clearly an issue with how C14 handles loading across cores. This is unacceptable, I’ve downloaded the Logic 90 day trial and I’ll run the same test and report back.

Why are you still running Ventura?

That my friend is a good question - I never update / update late for fear of stuff breaking. I am on Ventura 13.6.9. what are you running?

@davidlevymusic what OS are you running?

My test template runs fins in C12 and C13 in C14 it’s rubbish.

macOS 15.2

I was using Sonoma but things got so bad I thought maybe updating the OS will fix everything. Spoiler alert - it didn’t. So I’m currently on Sequoia still dealing with ridicules CPU usage and spikes.

why are you using AU plugins? I"m running C14 on an M1 Max MBP and it runs great. I"m only running VST3 though.

I’m on Sonoma 14.6.1

Sorry I am NOT running AU plugins I meant VST plug ins the only thing that makes a difference is AudioGridder - really drops the resting processor usage.

I am going to upgrade to Sonoma and report back.

Right starting to get very annoyed with Steinbroken now. Have uprgaded to Sonoma

Same template in C13 and C14 under Sonoma 14.7.2 ooh nice backgrounds…

C14 Idles like a car with snapped camshaft - very high and lumpy idle then every 10-15 seconds wham massive spike to red.

C13 Same template idles smooth.

For me it’s definitely C14, not the Machine or the OS. Same template in my trial version of logic idles like a Rolls Royce.

My one day off to make music and I am trouble shooting this bullsh_t instead of pursuing my hobby. Good job I don’t need this software to make my living.

have you tried trashing your prefs and updating your template?

C14 runs great on my M1 MBP

Hi

Yes tried that too - it is intensely frustrating!

Also Sonoma broke MS Office and One Drive so it’s not just Steinberg to blame here.

Thats weird.
Are the audio settings like resolution and buffer set to same values?
M1 Pro Notebook here and no problems at all with such things. OS is latest Sonoma.
Are you using Cubase in Native Silicon mode?

ps: office runs fine on Sonoma here, too.

I’m running a Mac Studio and Sonoma and I’m not having performance issues. Running Kontakt, Musio, UVI etc

I did have issues initially to do with my i/o audio connection presets - and had to delete them.

Hi

Everything is the same in the two templates between C13 and C14.

I also run UVI and the Pace Elicensor also broke during the upgrade. @basicnoise did you cold start with Sonoma or Upgrade?

@Manike I will also try that but my test template is all VIs outputting to the stereo master.

Thanks for all the thoughts this is super helpful and knowing that some folk are running Sonoma hassle free is encouraging!

Try starting a project without the C13 template.

Users have run in to performance problems before using Templates created in previous versions.

Hi, I just upgraded.
never did a clean install since I bought the MBP in 2021.
Do you run Cubase in Rosetta or Silicon Native mode? Changing this made a noticeable difference on my system.

It’s a mirror template made in C14 with the same VIs but thanks for the suggestion.
