Any suggestions tips etc as to why I am only about to utilize half my CPU power on a quad core Intel I5
Cubase registers at 100% and crashes but CPU load is only registering around 40-50% max
I have turned on multi-core processing and disabled power saving in Cubase.
The current test I am running is with Amplitude 3 64bit (I have tried other VSTs but same result)
I get to 12 instances of the plugin then I get the crash message… Then the Disk meter peaks and overloads, it goes from 0 to 100% when I open instance 12. I have tried this in the demo verion of cubase 6 and it also has the same result.
You can’t compare Cubase’ ASIO performance directly with the overall system performance, different views.
The performance you see / monitor in Cubase, is an ASIO audio driver performance, which only have priority to use up some of the total cpu / system time. There is more task, jobs in windows that has nothing to do with audio, and that also needs some cpu time. So that’s why you not see a completely maxed out cpu.
@split, yeah it looks like it’s an Amplitude 3 issue now, I tried other pluggins (Waves IR-1, Aphex Aural Exciter and SPL Virtalizer MK2-T) and managed to get to 50 instances, so it’s not a cpu load issue anymore ,it must be something to do withthe way Amplitude 3 accesses the hard disk, could be a bug, but how many people would ever really use 12 instances of Amplitude 3 (I was just using to test load).
Now I wish I knew what I did to improve cpu load, I tried so many things in the last few days, I don’t really know what actually made a difference. One thing that I have done though, is change from 44.1 to 48 sample rate. You would think that would use more cpu, but it seems find, so it will be intereting to see how it performs.
