Re: Nvidia GTX 660 Ti not working with Vegas

Well... I do own a Gigabyte GTX 670.. And its working perfectly...
I do not get any faster render times, But Vegas Pro 12 is stable as a rock!

Never had problems with drivers or anything... May be your old drivers/files laying around in the system?

Have you tried format you disk and reinstalled windows ?

And it looks like the GeForce 600 series GPUs are not the only GPUs affected by this bug. I dug further, and also discovered that users of Vegas with K-series Quadros are also having the very same problem as those with GeForce 600-series cards.
Well Randall.... In Video FX tab in Vegas Pro, you have "GPU Accerarated" plug-ins...
They do actully use cudas for faster playback speed... In Garys Video (Sony Staff) he shows that Vegas Pro use the GPU for both playback speed and render.. When it comes to render it does not use GPU for all outputs...
On Sonys webpage the "XDCAM EX (MPEG-2) 1080-60i Render" and "AVC (H.264) 1080-30p Render" is listed as compatible...

it maybe others, but I have no insight in them.

And yes, the 600 serie isnt supported or listed at sonys website.

Iam no programming engineer, but I read on Sonys forum something about the newest CUDA toolkit/api (whatever) which is in the 600 serie cards, isnt implented in Vegas Pro. Why? Idont know.

Kim,

I stand corrected. I have not been following Vegas developments closely since I "defected" to Adobe some time ago. (And that was around the time of Vegas Pro 9.0, which did not support CUDA or OpenCL GPU acceleration at all.)

Re: Nvidia GTX 660 Ti not working with Vegas

OK =)

The only problem with Vegas Pro's GPU acceleration is that it havent been updated to support the 600-serie graphic cards. And I dont have a clue whats up wih ATI's graphic cards.. Never tested them.

Yeah, Adobe have so many good stuff, such as buffer on a scratch disk. Very effective... I meant After Effects... Dont know about Premiere?

Re: Nvidia GTX 660 Ti not working with Vegas

Slightly off topic, but since you mentioned Adobe, I wonder if more people will be upset with their cloud idea and move to vegas OR, will more people like that idea and move away...

Adobe customers can use CS6 on their machines with out upgrading to the cloud and from what I read that is the last version they will sell as a package you can buy at a one time cost. Since CS6 is fairly new, Adobe customers will have a few years before they are forced to move to the cloud as technology changes.

Microsoft is doing office 360 cloud now, to me it looks like the world is going to shift to this cloud idea and that means monthly fees will be added to our way of life again.

I think we have a few years left to pay off the mortgage so we can switch to a software mortgage instead.

Re: Nvidia GTX 660 Ti not working with Vegas

For video playback in VP 12 the nVidia GTX 660 Ti card is recognized.
My experience with the GTX 660 is that when I turn off "GPU acceleration of video processing" in VP 12 my card usage increases significantly. With acceleration turned on the Usage never peaks above 14%, but when I turn it off the Usage peaks to 24% and a few quick jumps to 30%. No expert in this area, just an observation. I am using GPU Meter as my source of information. I am using latest Neat Video and some NewBlue effects.

I assume the CPU is doing the heavy lifting since either way the frame rate remains 29.970 Preview(Auto).

Re: Nvidia GTX 660 Ti not working with Vegas

Just want to share my experience with AMD card. I am running Radeon HD 6950 2gb with a 3930K overclocked @4.6Ghz 6 cores. 64gb DDR3 running @1866mhz. Was running @2133mhz but back off to stock speed 1866mhz.

Vegas timeline performance is awesome GPU Accelerate at 94% and only 1% on CPU. I can scrub avchd footage (60D footage) on the timeline smooth like butter. No jumpies nothing


GPU Accelerate render performance. MainConcept MP4 GPU



MainConcept MP4 GPU load 93% CPU load 14%
Sony AVC GPU load 38% CPU load 28%
Mpeg2 Blu ray GPU load 28% CPU load 87%

Most people says go with Nivida cards 5XXX. But I Prefered AMD for 2 reasons. 1) I am running 3 monitors in Eyefinity setup. 2) I want maximun timeline performance. A+ on video rendering, AMD card did very good for me, as you can see above.
