Options>General>Disable multi-processor AVI rendering
I guess one should check that's unchecked.

Thanks Bob. Guess that's where I might have looked. Most likely checked as a default. Still jugging along nicely, however, compared to the older machine. The new is a 4800.

only other thing you want to do is go into your preferences tab and set the number of threads that you want Vegas to use.

Options -> Preferences -> video tab -> maximum number of rendering threads.

I think I heard something like it should be set to 1 thread for each core, but that' might be totally wrong - maybe it should just be set to 4 or something.

I've only been able to get Vegas to see one of the cores on my amd x2 4800 dual core per render, can only get the procs to hit 50 percent usage. Of course you can do the multiple instance thing and render two sections simultaneously, that gets em up to 100 percent real quick.

Anybody have any tricks for 100 percent usage with a single render or am I missing something...which is probably likely...

Thanks

On my dual Xeon all 4 'cpus' run during encoding but only to 65%. I'm pretty certain the disks cannot keep up. Rendering doesn't not scale well across multiple threads unlike encoding.

"if I wasn't rendering at the moment I could look for myself"

You could always open up a second instance of Vegas while you are rendering.

Excellent call Kelso!! I hope I'll remember that on. - G

just a quick report - yep, I'm a moron. Must have been some the media I was working with - right now rendering between 60% and 90% percent from Cineform to WMV.

That will teach me to post late at night...

Bob - from what I've read, HT procs (as far as I know Xeon procs are HT) are best in Vegas with the HT turned off in your bios.

you may remember back last year, when their was a big stink about how it was actually taking longer to render in the new version of vegas. Well, that was because HT doesn't actually give you two cores and so the it takes up more resources to split up the work than it gained from sharing the workload, because it wasn't really having anything to share it with. Now with 2 HT's you'll see 4 but really only have like 2 1/2 or something (disregard the math that doesn't really make sense here) and you may find better performance with it off than with it on.

Anyway - just incase you didn't know.

and feel free to correct me folks, if I'm wrong (which is HIGHLY possible).
