ok thanks!
i will check this on the new laptop.
another question:
will this have an effect when i use my laptop with battery?
(i think it will, but just want to be sure)

is it possible the duocore could perform quicker or more efficiently?


I don't know if these questions have been answered on the forum, I try to keep up with all the Live 6 stuff because I am about to do a major hardware/software upgrade. More info needed...
You seem to be mistaking Core 2 Duos for quad cores or 2x dual cores. It's neither... It's just 2x64bit cores as opposed to 2x32bit cores, that's what makes it "Core 2".

AFAIK the difference in performance between 64 and 32 bit in Live is non-existant at the moment (as neither Live nor Windows takes advantage of 64 bit yet), so that'll just be raw clock speeds that count.

The Mac Pros and some other higher end computers have two dual core processors (ie. four cores), but that's got nothing to do with Core 2, which is just a different dual core processor.

I'm running a Core Duo 2GHz laptop and I have a question which I had hope the 6.0 release would clear up. In short, I start getting audio glitches when the CPU meter approaches 50%, whereas I would expect this to occur nearer 100%. When I was running v5 I guessed the explanation was that Live was only running on one core, so only 50% of my CPU could be safely utilised.

But the upgrade to 6.0 didn't change this, and overall, I haven't noticed an improvement in performance either. (At ~10ms latency, 1 instance of GR2 and 1 instance of Dimension Pro are still enough to challenge this system in some cases.) And in retrospect, it didn't make much sense to think that a CPU meter in a single-core app would be aware of CPU power it couldn't use...

So what's the deal, should Live 6 be choking at 50% CPU? Does anyone else experience this? Any ideas?

I hate to ask, but did you make sure that dual processor support is enabled? It's in the prefs somewhere.

Anyways, if you're getting dropouts at 50% I reckon you might need more RAM or you should maybe try to trim you system down a little.

:oops: :oops:

You are right, I was mistakening core2duos as quads. So, then Would it be smarter to shop for just duocores if they have a faster clock than the core2duo.

'pends. If you're buying a Windows computer you might have bought a new one before MS gets their arse in gear and makes their OS 64 bit, but if you're buying something top of the line to hang on to for more than 2-3 years, it could end up being a bigger issue than .3 GHz or whatever the difference will be... Nobody nose*, though..

well shit, this adds a new dimension to buying a notebook now.

Are only Core2duos VISTA capable, or duocores as well?


wasn't veggyman or whatever his username is getting stellar results with VISTA?

To be honest I'm probably overstating it. It matters on Macs cos the OS actually cares and will give you the benefits of 64 bit hardware.

P3s are Vista compatible, in theory. Vista isn't 64 bit anymore than XP is to the best of my knowledge, and only servers run 64 bit XP as nobody has drivers or apps for it.

There was someone who claimed that, yeah. I'd wait a bit for some more down-to-earth reports if I was you... and for some better explanation of which of the 16 different versions you want to get...

Thanks for the feedback, noisetonepause, but yeah, I've enabled the dual CPU setting in Prefs - I even tried enabling the Dual CPU for Rewire setting, even though I never use rewire...

I'm pretty savvy with regards to optimizing a system for audio, so I don't really know what could be happening here. I have 1G of RAM. And if there were other s/w processes bogging the system down, I'd expect that to reflected in the CPU meter.

Weird.
