I have a Mac Pro from early 2010 which I used to run via Bootcamp to boot Windows XP. I used Cubase SX 3 as well as 5 on this system. Performance overall used to be great, apart from the 1GB RAM limitation from windows XP.
Because of this, I switched to OSX 10.7. I did a clean install of everything: OSX, Cubase 5 plus Kontakt and Omnisphere and some waves plugins as demo.
Since the switch to OSX the performance is terrible… I have a session with 2 instances of Battery, plus one instance of Omnisphere. Two audio tracks, no further plugins used, buffer size set to 128 on a RME Fireface 800. I get CPU spikes all over the place.
Impossible to work like this!
Obviously I don’t want to up the buffer size because of latency. I used to run 150+ tracks on Windows XP with 10 virtual instruments plus many many plugins; no problem. Now, the system craps out at 3 vsti’s and a plugin… What is going on?
I tried both Cubase 5 and 6, 32 bit, 64 bit. All the same. I read about OSX performance being not as good as windows for Cubase, but this is a joke!
