sooo, waht about my ambience count..bad/good?

dunno - I think AMDs internal cpu-rating is pretty much messed up... - let's see... - you've got about 28% more power under the hood than me - you have a 3000+ and I have a 2600+ so your performance seems to be pretty good...

aha, I was kinda nervous...ok then, I might mention that I used preset 13 (no modification)

HI

The only reason to run Ambience in tests is that you will run into a brickwall quickly - it's an absolute pig-hog of a mother.

When I get the latest SXV3 up-date I will post my dual Xeon DAW findings - I previously got 12+ but got bored with the test!

I think I can come close to 'ttoz' - which will upset him - I might go test the SX ver of Ambience which I think is a lot lighter on cycles?

That would make up for the Logic optimizations.

Flipper.

Then do it!

I just tried this simple test on my system using Tracktion2 (Athlon 2.8 on a shity kt333, Audiophile 2496@128 samples, 44.1 KHz), just for the heck of it, and 6 instance of Ambience is all my system could do which gave me about 70% cpu used; the seventh instance brought the cpu to about 85% but it was clicks and pops all over . Probably a similar system with a better chipset than the crap I'm running would get one or two more instances, but I would guess not much more. 19 instances is enough to impress me.

try the asio4all-driver instead of your native one - it gives me seven instances without crackling and e-to-e still enabled @128samples

THE key feature of Logic, just as ttoz allready mentioned: It won't start to crackle on higher CPU loads. On my Ambience tests I could theoretically run as much instances under SX as under Logic (as said, on PC that is), but in SX I was getting the first crackles at around 65-70% CPU useage (according to XPs CPU meter) whereas Logic was running fine up until around 90%. I could only get as close to that in SX when raising latency to a value rendering realtime playing of VSTis unuseable (1024 samples, IIRC).
In addition, on my "mixed" tests (VSTis, audio tracks, audio plugins) the differences were even more noticeable.
And of course then there's dynamic plugin allocation, which should again give you a fair amount of CPU cycles saved on average projects. But I ruled that out on all of my tests.

I really wonder why they don't get this sorted in Cubase land (apparently they don't get it sorted as well in any-other-sequencer-but-Logic land). Yeah, 5.5.1/PC has got some massive flaws, but regarding efficiency it's amazing that a 3-4 year old audio engine (since it's still the one introduced with 5.0) is still kicking most others butts.

The ASIO4All driver introduced an audio recording offset on all systems I've been trying with. But then, I haven't tested the new one too much yet.

Tracktion works the same way here - the cpu is in the red (more that 95% of cpu-usage) and still no crackles...

you can adjust this with its advanced settings...

I seem to remember (a long time ago) instead of crackling, Logic would just stop. With a courteous error message, of course.

Which pissed me off no end. I'd have to restart playback, instead of enduring a few crackles.
