This is not Sony's fault but rather Nvidia's. Nivida made changes to the driver that crippled the GPU acceleration for Vegas but improved gaming performance. Is there anything wrong with 296.10 on your system?
Vegas can make use of both GPUs but it does better with SLI switched off or if you select "Activate all Displays" in the control panel.
You have to experiment which GPU is selected in the preferences. If I select the one that is in the physically lower slot then both cards will be active during renders, this only applies to rendering with MC AVC codec but there is a good 30% performance boost with two cards. Check Hulk's benchmark thread.

Even I would get a Quadro in place of my 2 GTX570 if there is proof that it is any faster but there isn't. GTX570/580 are the fastest cards as of now.

Fair enough. I ordered the Quadro for piece of mind, not necessarily the fastest card.

It is a pain that newer cards are not any better and that even pro cards are not. The top Fermi based Quadro is the Q6000 and if you look at its specification it isn't even as good as a GTX580 but it does cost a huge amount more. I think Nividia made some hardware changes too to protect its own a** as there many software hacks available that will turn a GTX580 into a Quadro card in the eyes of the software. I know as I did that for my 3D app and it works great!

I have never had anything but trouble with NVidia software, such that I now make a point of never installing any of their utilities.

I really have never had any problems with nVidia for the longest time.

I was quite happy with the performance I was getting out of Vegas with the GPU.

Obviously, this isn't a hardware issue, as the card worked before, and with earlier drivers.

My main complaint is that Sony keeps touting GPU performance, and it doesn't exist in nVidia.

You would think Sony is big enough, and could apply pressure on nVidia.

Otherwise, Sony drops the support and throws the weight to AMD. That might wake up nVidia.

I guess there must be enough money in the Quadro cards, that Sony is still pretending that the stuff works.

I can tell you the stupid GeForce Experience keeps throwing install errors. Maybe that's the root of the issue.

It just kills me to have to purge out new drivers for old.

It also pisses me off that Sony is completely silent on the issue.

So what's the take-away here? Yank my new NVIDIA card?

My copy of Vegas just doesn't work anymore and I'm ready to clutch at straws.

Sony will run on a computer with an nVidia card, you just can't use GPU assisted rendering unless you use an older driver.

M

Not on mine...

Sony made it very clear that "FERMI" cards are the ones that work.

"NVIDIA recommends NVIDIA Quadro for professional applications and recommends use of the latest boards based on the Fermi architecture."

I think the reason SCS doesn't come more forward might by agreements with both sides Nvidia and AMD that doesn't allow to favor one or the other. I am sure both sides helped to implement the render codecs and don't want to see a swing to one or the other side.

Many of these things are "politically" connected, we don't know the real back ground, and we as end users are the ones suffering from such politics. Thats is all pure speculation of course.

You can't get Vegas to launch at all?

If that's the case, I've had the problem before, and most commonly found it didn't like a VST plugin I had installed. I do lots more audio work than video work.

I've also had it hang up on ASIO drivers.

Are you saying you've had Vages work with a differen video card, and just not with an nVidia?

M

No, it runs, but has been crashing frequently. I have somehow cobbled together a 6 1/2 minute 3D video but cannot render---even with the GPU disabled.

It used to work and your thread reminded me that one of the things that have changed is the new Nvidia graphics card.

Well, I can tell you I haven't had any problem with Vegas running on my GTX 580's since I've gotten them.

The lock ups I've had, as I mentioned has been due to VSTs or ASIO.

I kept also having ASIO issues, and I had to re-enable my motherboard sound, just to redirect windows to it, as windows kept interfering with the ASIO card.

And I've used a bunch of different nVidia drivers.

To answer your original question, we'd never ever know. We aren't privy to know how the complexity of issues would conspire to stop it working for you. Barry's suggestion in investing in a card that appears to cost as much as the PC would provide you with the entre into the "support" opportunity to ask directly of SONY why it might not be working. If the latest drivers don't work and earlier DO why persist in banging your head against the wall to try and prove something? A Pyrrhic victory.

IMO, Barry has the correct attitude: Buy the QUADRO and get the opportunity to ask these questions of SONY. Don't buy it and you can't. Or have I got it wrong?

I have a 2GB NVIDIA GEFORCE GTX 560 Ti and a driver that is almost a year old. When I have issues I bash ASIO or rescan VSTs, or delete previous build and install. Unless I can hear or tell of some unequivocal benefit, what I don't do is update the NVIDIA drivers. Until I hear unequivocal evidence from SCS confirming it, I suspect I'm not going to get the SCS "support" from updating my Card's drivers. It can't be both ways.

Cheers

Grazie

Until I hear unequivocal evidence from SCS

unfortunately i think that's what we're all hoping for grazie....

To answer your original question, why does it need to? ( ...get Vegas to work with anything even close to a modern release of nVidia drivers. )

Why change drivers if you have a version that works? Particularly if you have an older card ( 6 mos to a year ) that is stable with the drivers that were issued when the GPU was considered mature.

Driver releases are usually accompanied with fix information, and it the fixes do not address a problem you are having, it is much more likely for you to encounter a new problem with the update..

If the fixes include a generic " improved performance " you can be assured they did not verify that improvement would happen with Vegas...

If you must update " just because ', then it is always a good idea to back-up things beforehand..

Vegas, like any program has it's share of problems, but being responsible for 3rd party hardware and drivers in all scenarios, is not one of them.

You need to look to Nvidia to assure their comparability, not the other way around; but I wouldn't hold my breath when it comes to hardware aimed at gamers and not video pros...

I'm using the NVidia Titan card with the very latest drivers. I even use BETA drivers on release day and having no problems with Vega Pro 11 32bit and latest version of VP12 64bit. Just an FYI
Is it the world's greatest performance available? Maybe not, but everything is running fine.

wwjd,
Are you using GPU preview acceleration and render assist in supported codecs?

Did you participate in Hulk's benchmark test?

I've got GPU on most of the time. Sometimes certain renders crash so I render CPU ONLY and then it works.
Far as rendering goes, last time I tried the SONY TEST, GPU only got me a few extra seconds of speed.
It's not a smoking card for video editing renders at all, but it seems to work fine with the drivers.

OLDSMOKE, have not tried Hulks test, but will. I have an i3770k non-OC 3.50 speed, 32ram, 10k drive

I hop tween VP11 32b and VP12 64 a lot so I can't remember what works well where. :) But they do work.

erm... where's the DL for Hulk's test? I found the thread, but are they using the SONY BENCHMARK project?

Yes, the SCS Benchmark project is used for it.

wwjd says:
Sometimes certain renders crash....GPU only got me a few extra seconds of speed.

No crashes for me with any renders...
Main Concept 1080 30p GPU renders are 3 x faster than CPU for me on the Sony test..

That's with a 3930K @ 4.2ghz..

Can you run Best/Full video preview with no stuttering ?
