I know the slow export bug on Apple Silicon has been reported on earlier versions, but I recently upgraded to Cubase 13 and I’m disappointed to learn this still hasn’t been fixed. Exporting is slower than real time! A 4 minute project takes longer than 4 minutes to export. That’s obviously not correct behavior. The 8 performance cores on my M2 MacMini all show less than 50% utilization during the export. I can see reports of this bug on Cubase 11 and again Cubase 12. Is there any news on the status of a fix? ---

Just in case you didn’t notice, there is an option in the export window that says ‘export in real time’, so maybe it’s on. ---

No, it’s not 🙂 This bug has been reported many times. AFAIK, it affects all AS Macs. ---

Studio One has (or had) a similar issue. Think it has something to do [there, at least] with the export being done on eCores instead of pCores. ---

The activity monitor shows the performance cores are being used, not the efficiency cores. ---

In general the Apple Silicon Macs are super beastly but I never noticed much improvement when it came to exporting and even loading straight from the internal 4TB SSD with a transfer speed of multiple gigs a second. sometimes the numbers just don’t mean much in the real world. ---

Apple Silicon is plenty fast, that’s not the issue. The track counts you can get are incredible. There is hardly any I/O happening when you do a stereo mix export, so it’s hard to see how it would have anything to do with transfer speeds. It might be a cpu scheduling issue, but it would be nice to get an update from Steinberg on this. I’m sure they’ve been looking into it for a long time now. ---

One other observation: With most DAWs when exporting/bouncing, the cpu is almost fully utilized, with the performance cores running at 80-90%. In Cubase when exporting, the cpu is lightly utilized, with the performance cores only running an average of about 20%. Not surprisingly, this means exports in Cubase are much slower than exports in other DAWs. ---

I’ve only just had to do this… Oh dear - It’s really depressing - especially if there doesn’t seem to be an answer to it yet… I’m on a Mac Studio M2 with Cubase 13 Tried exporting single piece of audioo through a few standard plugins and it’s only 4 times real-time - which means an hour long audio master is taking 15 mintues or thereabouts - was never like this on earlier versions. Just for a test I ran as near as the same I could get away with through Audacity - and it did the whole thingin juts over a minute - 50x speed - that’s more like it. So what happened to Cubase? And what’s it going to be like when I want to really put it to the test with massive project full of audio and VSTs as well?
