Cubase 6 more CPU hungry than Cubase 5


Thanks for a great upgrade.

I just performed a CPU test, opening the default preset in both 5 and 6 and simply loading and playing back the same audio file and it looks like the 6 is more CPU hungry than the 5, according to the CPU meter (f12). For this test I set the buffer to the lowest my card would allow (64).

Can somebody confirm that that’s the case?

Is that normal for the 6 to be a little more CPU hungry than the 5?

Thank you,


Hi xactsound

if your playing audio file thats on your HD, unless you have any VSTs that have not been recorded your cpu should be quite happy on cubase 6 and 5

Aloha sasha,

I have not done any tests but for me have I definitely noticed cpu jumps going from:
SX3—>C4—>C5 but not C5—>C6 which surprised me.

Perhaps I am wrong on this but if there is a cpu usage jump using C6,
I have yet to see it when loading/using songs done is C5.


I can confirm this too but I wouldn’t worry too much about it

Thanks for the replies.

Yes, I can now confirm that the C6 is slightly heavier on the CPU than C5. But nothing to worry about unless you have a weak machine or running a really heavy project.

Thank you,


They did ad a new, better realtime stretching algorithm. Might this be why?

In some occasions I felt Cubase 6 even lighter than Cubase 5. But this changes, when I use HalionSonic SE. And I am talking about a Pentium 4 with Windows XP, way below the recommended minimum…
