one thing you should try after updating GPU drivers is resetting Vegas to default (CTRL+SHIFT while starting) then disable GPU, restart computer, open vegas in the default mode you just set and then re-enable the GPU acceleration, sometimes Vegas registry keys point to old drivers flags instead of new ones, so it doesn’t hurt to clean the house a bit after installing new drivers.

[James Fullerton] “I guess I will test a few cards and see what happens. I think the Quadro 4000 will be first, and then who knows what. I’ll post up details for sure.”
I got Quadro at work which makes things easier, but at home where I try to stay away from work (impossible !) I have several AMD and Nvidia cards lying around, I would suggest to avoid AMD for now since OpenCL support is not as refined as CUDA, when it comes to Vegas Pro, even if AMD cards are faster computing hardware we don’t have actual software taking advantage of them so… Nvidia it is, and for now if you’re not using OpenGL video FX such as the ones from NewBlue, 570/580 are the cards to buy until 6XX – 7XX series are fully supported in next Pro 12 builds or Pro 13.

[James Fullerton] “Is there any way to guesstimate what kind of performance increase I will see if I go to the 580 card? 5%? 50%? 100%?
Is there any indication that Sony is going to provide updates to Vegas to utilize the 6XX series cards? It is a little concerning to think about the fact that the GTX670 FTW+ has 1344 Cuda cores (of which Vegas is only using 336) whereas the GTX580 has 512, but what happens in the future? Will Sony add support to the 6XX series cards, and then I lose out on the 1344 Cuda cores in the long run, for essentially the same price?”
performance gains depend on the video effects compatibility with GPU rendering and your desired output, using Sony AVC I’d say the performance gain with a fully supported GPU such as a 570/580 is certainly above 100%, if you have the RAM and CPU not bottlenecking your GPU you will see improvements up to 5x faster rendering times with optimal templates, codecs and effects.
as for the 6XX series, look the new 7XX series due this summer are based on the same architecture but with further performance tweaks, so in order to support them Vegas will be supporting the 6XX at the same time, of course when fully supported a relatively cheap 660 Ti is a more sensible buy than whatever 570-580 you could find due to better performance, way less power consumption and heat, the Kepler GPUs are a superb when it comes to power efficiency.
Also don’t forget the 6XX series have a hardware encoder/decoder separate from the CUDA cores, NVENC, if this gets support by Sony the rendering times could be improved dramatically, again… when fully supported, something we don’t know for sure it will happen or not, but as I said it will happen eventually since the 7XX is based on the same architecture.

[James Fullerton] “hat kind of performance do you see with the 570? Can you give me an example of a format, clip length, and the resulting approximate rendering time?”
Intel 3770K + 16 GB RAM + GTX 570
I get 1:1 rendering times for 1080p 30 fps high profile – best quality Sony AVC templates using GPU, but depending on the video effects I use and their compatibility with GPU usually I get renders faster than realtime playing, the 3770K is “only” 4 physical cores + 4 extra logical cores (hyper-threading) but its single-core performance is unmatched until the new 4770K rolls out.
Titler Pro 2 on the other hand takes 2x times to render compared to previewing using a 660 Ti while the 570 takes 3x-4x, in this case the Kepler architecture is put to good use, if only the whole Sony Vegas software would fully support the Kepler cards and not only certain parts of it….

[Maibam Bankim] “My pc configuration are – NVIDIA GFORCE 9500GT, 1TB HD, 8GB RAM, INTEL CORE(TM) I7-3770CPU @ 3.40GHZ AND”
you are most definitely running off either VRAM buffer or just rendering power…. excuse me but why are you running a low-end GPU from 2008 ? your CPU is up to date and suits Vegas Pro amazingly well, multicore with powerful single-core performance, but everything is being held back by the 9500 GT. If money is a concern you can buy a 560 Ti off e-bay or similar place for very little money and experience an incredible performance boost, your actual PC build is not balanced at all and you know for most software your computer is as fast as the slowest of its components, in this case your GPU is more than slow, doesn’t belong with the rest of your good hardware.

your specs are good enough for a smooth Vegas experience… but unfortunately the 6XX series are not supported for every codec yet, you should be fine rendering to Sony AVC though, as long as you’re under the 314.22 WHQL drivers… personally I use a 660 Ti for Titler Pro 2 rendering sice NewBlue make good use of the superior Kepler performance, but for everything else I turn the power on for the GTX 570 in my system.

[Anthony Desjardins] ” i also noticed that while rendering, my processor is only using 4% while my ram usage is at 91%”
to me looks like you have GPU acceleration turned on and the card is recognized by Vegas Pro, but unfortunately it just sits there doing nothing, update drivers, disable/enable GPU and try again… what is exactly your GPU model and drivers ?
-
what I did learn using Vegas is that GPU rendering is causing more headaches than benefits, specially for 3rd party plugins, you need to test effects one at a time or combined with others, they are so expensive compared to the poor GPU compatibility and stability, not everyone can afford a Quadro at home, and even with Quadro you have issues with most plugins and GPU acceleration.

sorry got the wrong number, actually my Titler Pro 2 updated to build 130405, so many versions and builds everywhere…
there it is consuming over 1 GB of VRAM just by editing, luckily my modest 660 Ti at home has 3 GB of VRAM… not the Quadro at the office but it works fine editing and then switch to an older GTX 570 for rendering until 6XX series are fully supported, if I’m just rendering Pro Titler 2 stuff I use the 660 Ti which is much quicker for that purpose.

the 660 Ti runs very cool, but your AMD CPU not, check that the CPU heat sink is properly and firmly attached, you might want to dust it off, take it out and apply a new layer of thermal paste on the CPU after cleaning off the old one, then mount the heat sink back… if you’re unsure how to do this visit your nearest electronics, how about going for a water cooling solution ? once you get one you’ll never go back, it’s not expensive and well worth investing into, in my opinion.
