I have been getting real time cpu peaks and as a result audio drop outs running virtual instruments for a while now. It doesn’t seem to be one in particular. I am on a fairly powerful system (Late 2013 Mac Pro Trash Can OS X Sierra 10.12.4 / 12core / 64GB Ram with 1st gen UAD Apollo Quad via TBolt 2 / Caldigit T4 raid via TBolt 2) and still it will intermittenly peak with only a few VSTS. I even get this sometimes with the buffers kicked all the way up (2048). I was previously on a 2008 Mac Pro 8 core and never had the real the time peaks and drop outs I get now. I believe this is a Cubase issue and not system issue because when the CPU peaks the system doesn’t budge.
I have done the following so far.
-Completely removed and re installed Cubase 9.
-Completely removed and re installed / reset my Apollo sound card.
-Created a new profile and tested.
-Made sure I had all the recent OS updates.
-Cleared out all caches (System / User / Dyld).
-Checked all drives for errors.
I created a similar project in Pro Tools (sorry…i only use it to open others projects) and the CPU usage was much less and much less jumpy.
I know there have been may issues with the last couple updates (IE Mac Graphics) but I was curious if anyone has experienced this and if so has any suggestions? This is very concerning and has almost caused me to miss some deadlines. I have put in a ticket but am still waiting to hear back.
