Vegas will only see 4 cores

So today I got a chance to load Vegas 8 on a monster of a workstation, how much of a monster, well 8 x quad core AMD chips with 32gig of ram.

The problem is that Vegas will only see 4 cores on one chip which is fine for my single quad core station but what if you built a dual or quad quad core machine.
Does anyone know why it won't see all the cores and is there a way to fix it.

thanks

Multithreading is a beast to program correctly for, especially when the original design of the program was single-threaded. The fewer threads, the fewer crashes. So they put a cap on it.
 
With most other applications it has to do with how many cores your license will allow. The more cores allowed the more expensive the license. Not sure about Vegas though.
 
Quad Core Processor w/ Vegas 8

Quad Core Processor w/ Vegas 8

I currently have a dual core AMD 1.67 processor on my laptop (w/2 gigs RAM) and Vista 32 OS. It's great for editing SD, but now that I'm using an HVX and starting to shoot HD, I need to get faster render times. I am planning on purchasing a Quad Core desktop machine very soon, but want to know if the program is using all of Cores with Vista 32.

Is there any clear language out there that states that Sony Vegas 8 actually uses all four cores on a quad-core system?

I looked on the Sony Creative Software website, and it says that Vegas has "Improved multiprocessor rendering." I'm not sure if that answers my question.

Or do we have to wait for 64 bit version of Vegas to use all of the computer's processing power?

Any feedback would be great. If I upgraded to Vista Ultimate 64, on my laptop, would that improve render times right now?

I just got a quad core system (Q6600 2.4 GHz overclocked to 3 GHz and 4 gigs ram), and Vegas uses all 4 cores, but only renders at 50-60% utilization whereas other CPU intensive programs such as 3DS Max renders using all 4 at 100%.

Any way to improve this? It still renders quite fast, and editing HD is now a dream, but still...
 
Forgot to mention that it's running under 32-bit XP (and only sees about 3.5 gigs of RAM as a result, but nothing to do about that.) Rock stable.
 
pmark > but i even recently discussed this with many members here who conclude that windows 32 bit os wont recognize more than 3.2 gb of ram. How did u decide to put in 4 GB ? and is there any evidence that its using all the 4 GB ? Would be interested in knowing. Also how does one recognize how many cores are being used at a given moment of time ?
 
I knew that beforehand, but RAM is cheap and I managed to squeeze almost 3.5 Gigs into XP by turning off everything in the BIOS I wasn't using (printer and serial ports, built-in VGA adapter, etc.)

I really need the RAM because I'm doing some monster landscape renders in Max of several million polygons.

So far Vegas is using up to 2 Gigs on renders (but low CPU utilization, as I was complaining about before.) You can check by ctrl-alt-del'ing, then switching to the "Performance" tab. You'll see the load on all four processors, and below under "Physical Memory" "Total" shows how much system memory is recognized. Start rendering something to see load the system.

"PRIME95" really puts a load on the system. I used that, "CPUZ", and "CORETEMP" to help overclock to 3GHz (a 33% improvement!)
 
I have this problem in Vegas with a good half of my processing power seemingly always going to waste.

When rendering to DV AVI files Vegas would only every use one core on my duel core system. However, I just finished a project with Cineform (HVX200 material) and when rendering to a Cineform AVI it pegs both cores to 100%. Maybe it just depends on what you are rendering?

BS in this situation.

When I am sitting around waiting for Vegas to finish rendering something and I express my dissatisfaction that the tools I have are not working to their full potential how does that make me a poor craftsman? I have not yet developed the ability to give my CPU's a pep talk to get them to all cooperate, maybe you have.

Jump down off that pedestal and hang with us for a while.
 
Go into Options -> Preferences then click the "Video" tab.

Make sure that there's something in "Dynamic RAM Preview Max", even if you're not using it. Apparently putting "0" forces only one render thread.

Make sure the "Maximum Number of Rendering Threads" is set to the highest setting (in your case "2").

Also, in the "General" tab, make sure that "Disable multi-processor AVI rendering" is UNchecked.
 
BTW: I figured-out the problem of it rendering at only 50-60% of all cores -- some codecs are more efficient than others. Some render at a full 100%, some don't.
