CUDA Cores not working?

[Ken Mitchell]

What CPU are you using? If you are using an i7/Sandybridge it will take at least a GTX 560TI to transcode faster than a Sandybridge.. Does your video card have at least gig of DDR5 ram?.. That would be another plus..

I’m using a Phenom quad-core 3.2.
Yes, the video card has 1 GB of DDR5.

I bought this card because the CUDA cores are supposed to DECREASE rendering times with Sony Vegas.

Did you read somewhere that a GTS450 would be faster than a QuadCore CPU? I haven’t seen anyone get faster renders in Vegas from their GPU. I have a Quadro 4000 with 256 CUDA cores and Vegas renders slower with it enabled than my aging old original Intel 2 Quad 2.66Ghz. I keep it turned off.

Wish I could figure out this CUDA thing.

Vegas (10.0d) doesn’t even recognize the fact that I have a CUDA enabled card, even with the latest drivers.

Oh well ….

Apparently ATI also now supported according to latest Vegas Pro release notes.

“ATI GPUs
OpenCL GPU-accelerated rendering requires an OpenCL-enabled ATI GPU and AMD Radeon Catalyst driver 11.2 or later with an ATI Radeon HD 57xx or newer GPU (please see Known Issues regarding an incompatibility with driver versions 11.3 and 11.4). If using an ATI FirePro GPU, FirePro unified driver 8.773 or later is required.”

I have a high end quad core and an overclocked ATI 5870. I haven’t realized anything substantial. At this point there is no sense in us holding our breath waiting for this all to work better. It will in time. How long?…Who knows.

Well I thought that was the whole point of CUDA cores.

The original video card I was going to get had 16 CUDA cores.
I was told the more CUDA cores the better. So I went with the GTS450 which has 192. The guy who sold it to me said he gets about 50% better render times with his 64 CUDA core card.

[William Van]

How do you know it doesn’t recognise your CUDA cores?
How would you know?

I thought the CUDA cores worked with the CPU as added “extra power” for rendering.

[Tom Pauncz]

How do I know??

HDV project, Render As… SONY AVC/MVC, click custom, select system tab and click button Check GPU – it says No GPU Available.

Thoughts anyone?

You won’t see any performance with CUDA assist in Vegas unless you start with a seriously underpowered PC.

“The guy who sold it to me said he gets about 50% better render times with his 64 CUDA core card.”

What was he rendering? CUDA in the GPU is primarily for gamers. More cores makes faster rendering of shading and textures in games. Adobe Premiere? The fact that Adobe Premiere needs GPU support just to be able to do what Sony Vegas can do with processor alone should tell you something.

Your card seems to be underpowered…. My 2600K with 8 gig of ram will trancode Sony AVC for bluray about 10% slower than the GTX560TI I installed with 384 cuda cores and 1 gig of DDR5 ram. I suggest you might check out this link… read the whole thing…It will give you some insite on cuda tech and specific cards.(Not just for CS5.5). KEn
