Is vegas able to take full advantage of Dual processors and HT processors?

I'm always hearing about how Vegas 5.0 is only able to take advantage of dual processors because it will use one for Video and one for audio. Is this true?

If so, do they plan on changing this program design? (they should IMO)

BTW, Could this be the reason that my HT proc. kind of peaks at 50% usage combined in the Task manager, with one side, running higher than the 50% mark and the other below (looking like maybe it's true that one is running the Audio and the other "processor" (as it is viewed by Task Manager) for video.

When encoding to avi, Vegas is not especially multithreaded. One thread for audio and one for video.

When encoding to mpeg or wmv, Vegas will take full (or close) advantage of duals.

If you have dual processors, you can set up network rendering nodes on a single machine and see nice benefits, but I don't have any numbers for that.

Hyperthreading or dual processors are especially useful, when you are running more than one instance of Vegas at the same time, you can have one rendering, and still get snappy responses while editing in the other one.

In reality if you have dual Xeon CPUs you have 4 processors, I think?

they work slower that way for most things -- it is better to not use HT on dual xeons

XEON's Have I think, Always been (maybe not always but pretty close I think) Hyper Threading processors. (I know that they are now - Intel's website said so)

only recently have they been HT capable -- but ask anyone using xeons (like me) and they will tell you that HT is for the most part useless on dual xeon setups -- only in a few (very few) apps is there any benefit and in most cases - HT will slow things down .

only recent - i mean last 2 years or so a 2.4GHZ xeon was the first to use HT .. so in that time frame ..

there may have also been a 2.2 HT xeon i think ... but would have been very rare -- mostly you would see 2.8GHZ 400/533 FSB xeons .... i would take the newer 800fsb xeons any day over any HT enabled 400/533fsb models

Just to check out , somebody knows where's the switch to enable HT (if there is some) ?

It is done via the bios

Oh. I was looking through control Pannel and couldn't find.
In this case, I probably enbled it when I installed.
It's just that I find my machine not to be so fast these days. Probalby needs a "pep up tweak".
But I'll check the BIOS again next startup.
Thanks.
