I have a GTX 770.....but am I brave enough to try?? Always nervous if it ain't broke to start with...

(Nodding wisely) That is what disk images are for. I just had a backup image save my bacon this morning.

Hmm, this post and video have been up for several days, and hhmmm, no takers!
I am really surprised.....Guess this is pretty serious stuff!

Well the views on it have risen pretty fast in the last few days. I made this in hopes it would help people. :)

Hi All,

Thanks for sharing this Josh, I think you might be onto something but on my system I didn't notice any real world improvement in time however I did see more GPU usage (I think unless it was just coincidence with another app running or windows using the GPU at the time)

Details,

I spent a while playing with this just now I have just rebuilt my system and have fresh system image if it went wrong I wasn't going to cry so much!

System Spec as below.
Vegas 13 373
2 x Xeon E5 2643 @ 3.30 ghz
32 gig ram
780 TI 3 gig
550mbps read / write raid 0 array

Only changes to Vegas
OpenCL Memory Size Filter set to 3,000
10 Gig Dynamic Ram allocated

Tested 4k and 1080p monitored GPU with GPU Z

rendering out to main concept mp4 indeed does not appear to use hardly any GPU despite what you have checked it does however grab a chunk of GPU memory ~600meg for 1080p and 1500meg for 4k
Applying the tool kit for me did appear to show more GPU usage (spiking at 20% not working the GPU hard at all) however for me it had no impact at all on render times suspect my CPUs are still picking up the bulk of the work total ~80% utilisation both runs.
4k exactly the same limited or no GPU usage before hand some after but no impact on render times reserves uptp 14 gig of memory)
Interestingly the proxy creation does not use any GPU acceleration at all in both scenarios but I think that's mpeg2 so a different template.

I did notice for the mxf creation I did in Vegas so I had a standard set of files to test on both before and after the install that really uses the GPU properly ~50-60% (before and after so no change)

The toolkit did not appear to affect the general running of Vegas for me (or break anything that I have noticed yet)

So in summary there might be something in it but I didn't notice any real world improvement for me, perhaps if you are more cpu / system memory constrained you might notice an impact, something did seem to change.

IMO Vegas can muddle through with the newer Nvidia cards but certainly doesn't use them properly and 4k is usable but I wouldn't want to do a big project in it, their new catalyst products do appear to be better, hopefully that development work will cross over into the Vegas development pipeline

If you don't mind me asking, how well does a dual Xeon setup do in 4K editing? I am between building a 5960X or a dual Xeon setup. I am looking for a system where I can work without proxies and have preview of 4K at Full/Best in 8bit with XAVC-S and XAVC-Intra.

Hiya I'll be honest for everything but vegas it's good so the other programs I use like davinci resolve, blender etc. in 4k it works well but that's also using the GPU effectively as well. I can work vegas in full best without proxies at best full at 4k and just about get full playback with the setup above and those file types, interestingly if I drop 4k into a 1080p timeline it plays full best easily, go figure, seems happier compressing it like that than on the fly for the preview window! so I tend to work at 1080p and if I want to do a 4k render or look 1:1 pixel then I'll change the project back to 4k. Also worth noting I have somewhat unusual xeons i.e. I went 4 core 3.30 ghz x 2 most go more cores lower ghz but letting individual core spike to more if all not in use I get a more average all over response but I didn't because I don't trust developers to write effective multi processor code :-) but it's getting better.

If I was personally setting up a new machine for Vegas I'd just go fastest cpu I can find that's not a reflection on the Xeons they rock on stuff like a big memory hog render in Blender just for whatever reason Vegas is always a bit clunky, it works, it's stable for the most part but never silky smooth.

keep in mind I don't have a 4k monitor perhaps vegas plays better if it's direct output to 4k rather than having to compress on the fly

For me I noticed that Vegas really used more of my GPU and took about 70% to 100% off my CPU and put that load onto my GPU. However, you also have to think about that my GPU has OpenCL and OpenGL on it. So probably Vegas could be detecting that and using my GPU better. There are a ton of theories. I just happened to stubble on one. The problem is everyone has a different system with different system settings and render settings, so my results maybe different from your results or anyone else. Now I do notice that with the CUDA toolkit my project preview is smoother as I can always preview my stuff at Best-Full all the time. Where as without CUDA toolkit, and GPU acceleration on I could only do Preview-full or half.

Josh_Grid21 - mark me still very skeptical that we are talking anything more than a tweak. I believe it has been about 4 years since SCS launched VegasPro into a never never land of ill repute with GPU deployment. There have been well over 1000 posts in this and other forums about anecdotal experiences. But nothing , nothing at all conclusive about how a system designer might make VegasPro function optimally.

Yet, we know some other well known apps do respond favorably and reliably to certain changes in the system. A good example is getting Premiere versions to sit atop certain video cards with measurable improvement over the course of a large number of installation variables.

So far not happening here in VegasPro.

Well, I still say the effects differ from Computer to Computer. Sony doesn't really seem to be taking advantage of high-end GPU technologies that are out. But for me, this was my own personal findings. It's up to Sony to start taking note of the community and what's out there, start coding their software better to use both CPU and GPU together to really improve render quality and render times.

I updated to the Nvidia driver 344.65 just now and went for the "custom" instal rather than the "express" instal. None of the CUDA toolkit type selectable options appeared in the dialogue box so I'm assuming that the procedure descried in the video does indeed only apply to Movie Studio. I'm on Vegas Pro 13-373, Windows 8.1, GTX570.

@Peter

The Nvidia Toolkit is not part of any Nvidia driver, it is a separate download.

Oh yes. silly me. Downloaded it and installed and nothing seems to have broken :- )

Part way through the installation it paused to tell me that Visual Studio was needed otherwise some components will not function properly; I chose the disregard option to that.

It installed driver 340.62 even though I had already installed 344.65 rebooted etc. I had to reinstall 344.65.

Tested a short MP4 render. Alls well.
