Audio artifacts at 30% CPU load

Weird. I'm running Win7x64 on Dell desktop with an i7-860, and I easily get 50-70% before dropouts.

Got a Cakewalk/Edirol UA25-EX as my interface, 192-288 samples.

Working with a project now with 30-odd tracks, a bunch of instances of Alchemy, native Ableton instruments and effects, a few Guitar Rig 4s, and Ozone 4, and it gets up to 65-70% before I start to hear crackles.

I was watching a YouTube video in Chrome last night as I was working and didn't have any trouble (until Live crashed, anyway).

The latency is at around 26 ms. with 440 samples. I have a EMU 0202 USB 2.0-soundcard.

And I have no other processes running in the background taking up memory. Besides, I have 4 gb, and a SSD-drive, so it shouldn't be a problem.

I'm finding myself forced to bounce every track, then run effects, then bounce, then master, and then bounce - otherwise the glitching is just too much.

This is pretty frustrating. Perhaps a clean Windows install would help ...

Well, don't reinstall Windoze yet.

Pretty frustrating though because it looks like yr system should be able to handle it.

Same thing here. From where do you read a cpu load?

Because I have glitches when cpu meter in ableton shows between 30-40% and in the system activity panel I see about 80-90%, wtf?

I am on mac.

Don't know if it helps, but I have a 4gb Dual core laptop, and I noticed a big improvement in the amount of artifacts when I wiped everything recently and upgraded from Vista (32) to 7 (64). More than likely it was the change away from crappy Vista, as opposed to wiping all my stuff, because I never ran much else in the background other than a chrome window.

I also have Windows 7 64 bit. I think I will format the harddrive and make a clean install and try my Audio 4 DJ soundcard instead. Hope it helps. Though, frustrating, as I have to re-install all plugins! Hope they fix it soon.

I also have the same problem. Before I got the Virus Ti I just set the latency higher, thus decreasing the cpu strain. But with Virus I have to keep the latency no higher than 256 samples, otherwise the latency (with Virus) is too much.

It's very frustrating to use only 30 % of the computers capabilities.

No doubt!

Well, a fresh install of Windows 7 64-bit surely hasn't help. Everytime I start Ableton 8.2.2, Windows crashes with a Blue Screen of Death. This is really getting unbareble!

EDIT:

Looks like it wasn't Ableton's fault as much as Native Instruments'. Crashes only occur with Audio 4 DJ and not with my EMU. Strange.
