Vegas Pro 11 slower than 10e?

orca wrote on 11/20/2011, 2:24 PM

I just upgraded to Vegas Pro 11 yesterday with the $140 promo. And now, I'm just previewing a straight .m2t import on the GUI. Vegas Pro 10e can playback in real-time 23.976fps, while Vegas 11 can only playback the same clip at 10 fps.

I can't use the GPU acceleration, and my system is about 3 yrs old with Q6600 2.40GHz running Win 7-64bit and 10GB RAM.

I duplicated all the settings between the two apps, am I missing something here and it's actually slower if I can't take advantage of the GPU? Has anyone experienced this?

Yup, here's some reading material for you: Render Time Strangeness

Per the dialog in the refernece thread, you might try adjusting your Preview RAM &/or Max Render Threads.

Wow... that looks more complicated than I thought. Thanks for the posting Jerry.

In the mean time I might have to do with Vegas 10 since I a project to finish soon. What a bummer.

I just did a very quick and dirty test for you.

I rendered a m2t file at 1920x1080 50i and played it back on my Q6600 2.4GHz and 6GB memory with a GTX460 graphics card and I get the following.

With VP10e it plays back full 25fps with CPU averaging about 25%.

Playing back with VP11 and the GPU disabled i get full 25fps but CPU running at 75% average. Enabling the GPU it plays back at 25fps with CPU back at 25% average - obviously the GPU helps a bit here.

Edit: 2fps? - Updated. Finger problems he he.

Hi,

Surprized me too by 2fps. Willemt, I guess you meant 25fps, right?

orca, if you want I can do the test with your project with my 10e and 11 Vegas's and tell you what I get. Just dropbox the files somewhere and let me know. I personally did not notice performance drops switching from 10e to 11, but it might depend on the footage format, or so many other things.

Do you have many effects on your clips? If yes, did you try to turn them off, and check if there is still a big difference between 10e and 11?

Hope this helps,

This is only a guess, but incorporating CUDA support likely required a lot of rewrite of the basic Vegas code. It isn't simply a few new pieces of code on top of the existing product. If I am correct the next few iterations of the releases will have improved performance of selected features. Even the first upgrade of V11 reduced the required CUDA score from 2.0 to 1.0.

Frederic,

Thanks for the offer, but the file is really big about 17GB as it is a continuous speech. I'm not even talking about rendering yet. It's just that when you put the .m2t on the timeline and you play it back (space bar). Vegas 10e plays it in real time while 11 stutters. And there's no effects, no transitions, nothing. I don't have to do much of editing but to trim both ends so it's no big deal, but can't help to wonder why 11 is much slower.

"Vegas 10e plays it in real time while 11 stutters."

Have you tried checking your video driver version? (Run dxdiag and look at one of the display tabs).

Frederic Baumann wrote on 11/21/2011, 3:50 PM

And did you try to benchmark 10e vs 11 on other file types (MOV, MPG, ...)?

It would let us know whether the problem is m2t-specific or wider.

After you mentioned this, I noticed after I installed 11, I got a message your display driver might be too old or something along the line. But I only got it once. I tried to upload the driver from nvidia (GeForce 8800GT) and the driver they have on their website even older than the one from Win 7 (2009 vs 2010).

I ran the dxdiag. Not sure what I need to look for.

It just says: "No problem found."

Frederic,

No I haven't tried the other format as I don't deal with those typically. If you have any clips on those format you want me to try, I'll be happy to run a test.

I said to click on one of the display tabs in dxdiag. You can get the same information from the control panel, drivers and devices, and right-click on the display adapter. Dxdiag is just cleaner.

The latest driver for your card is Version 285.79 BETA
See: http://www.nvidia.co.uk/object/win7-winvista-64bit-285.79-beta-driver-uk.html

Steve,

I got that part. What I was trying to say was after looking at the display tab, I saw the information that I already knew so I was trying to figure out what particular information on the display you were looking for.

But anyways, thanks for pointing out a/b the latest driver. Don't know why I didn't find this one before. I applied it. And I can enable GPU acceleration. It improved the frame rate, but only to 15 fps top.

It appears there are countless variables, but I just upgraded from v10 to v11 and updated my video card and V11 took longer to render than v10 on the particular project I tested it on (47 mins v10, 53 mins v11). GPU acceleration was turned on.

Core i7 860@ 2.8GHz, 8GB RAM
previous card ATI HD 4550
new card Nvidia GTX550 (285.62 driver)

So much for rendering 1.9 to 3.9 times faster. (http://www.sonycreativesoftware.com/vegaspro/gpuacceleration)
I realize there are many things that make a difference in video projects and rendering, but I imagined that the average project would render considerably faster. I guess I have an active imagination! (still love Vegas Pro though)
