Hmm what happened (CPU Usage at ~5%) ...

So I reformatted, reinstalled Vegas 8.1 on Vista 64bit with 8GB Ram and Q6600 @ 3.0ghz

Before when I rendered uncompressed .avi files, I would get 100% CPU Usage and a lot of ram usage... which was good, files rendered fast and it worked well. As seen here

Now for some reason I get ridiculously slow render times and my CPU Usage is 3-5% which is silly.

Any ideas? I've tried maximum rendering threads at 4/8/16 and Dynamic Ram at 0mb, 1024, 3076...

I don't know what setting I had, but something is changed somewhere and it's making a big difference.

Heh, nothing has changed except I reformatted my system and re-installed Windows and Vegas 8.1...

Joe, are you comparing like for like renders?

The image shows that before the rebuild you were rendering from avi to avi with no effects (that I can see). Is the post-reinstall render test rendering the same clip with no effects or any other changes?

I just did a little test on a roughly similar length clip with no effects and, as no recompression was required, it put very little strain on the processor (<5%). I added a couple of effects to the clip and I was up to around 50% straight away (still rendering from avi to avi). I'm interested to know what settings you had that gave you 100% CPU on a clip that needed no recompression (assuming you want 100%, that is).

I am running Vegas 8.0c on a Q6700 with 4Gb (only 3 seen by the OS) under XP SP2, so there are other differences to take into account, but this might be a good thing to eliminate from the issue.

It was .m2t to .avi.. the first clip is a time-lapse, so took about 90 minutes for that small section...

And this project has many effects, it's the same project I used before, same section, I would render it out in uncompressed .avi before and it would do it relatively fast and use 100% cpu.

Now it wants to take 2 hours to render a 4 minute segment and uses 3-5% of my CPU.

So I'm just trying to figure out what setting I flipped wrong... or something...

Or if anyone knows where the settings are stored for Vegas, I have backups before I reformatted I can grab stuff off of :)

OK, sorry, the screenshot you attached shows a roughly 90 second clip being rendered with no effects in use (unless you've applied them at media level) so I was basing my comments on that.

Oh I understand, I just had that picture as a reference to show CPU/Ram usage while rendering.

It's just weird that it's acting funny after the reinstall, but I never remember doing anything special before.

figured it out for anyone who cares... :)

How to use the throttling mechanism to control network performance in Windows Vista

I remember doing this tweak before, but just forgot about it... FFFFFFFF to disable the throttling...

Now I'm seeing usage between 25-100% depending on what's happening in the scene (which makes sense) I'm just glad it isn't at 2-4% and messin stuff up

Went from rendering a 4 minute segment in about 30 minutes to rendering it in real-time 4:06 long, took 4:07 to render...

Joe, thanks for reporting what the final solution was.

Why on earth would modifying your network throttle affect a Vegas render?

Because all my raw footage was stored on a server connected through gigabit? And the network throttling is specifically related to media type files.

Anyways, it's lame that MS does that, but atleast they offer a way to turn it off. I just didn't remember to do that tweak, or thought I had already done it.
