GPU Accelerator?

2knowone2 wrote on 2/24/2012, 3:14 PM

Hey Guys- I'm new to the forum but have been using Sony Vegas for about 4 years now. (Currently Vegas Pro 11)
So my first question is how do you get the GPU acceleration to engage? How do you tell?
When I go to "preferences-video-GPU acceleration..." It shows OFF...Why?

I'm running: Win 7 x64
AMD Phenom II X6 1045T 3.14 GHz.
RAM:16 gb
Radeon 6800 1gb HD
...Should have plenty of power!
Thx

You need a CUDA enabled video card for GPU accelation. Here's a list from Nvidia

CUDA enabled video cards

Also do a 5062 search in the Knowledgebase and try "gpu acceleration" in the Forum search.

I'm curious if GPU acceleration would even make a difference when running that CPU?

You can read more here:

http://www.sonycreativesoftware.com/vegaspro/gpuacceleration

Your card is not supported:

"AMD/ATI

Requires an OpenCL-enabled GPU and Catalyst driver 11.7 or later with a Radeon HD 57xx or higher GPU. If using a FirePro GPU, FirePro unified driver 8.85 or later is required."

Hm...that's a bummer!
Does it make that much of a difference you think?

I have a Radeon 6800...i't's pretty new. a little over a year old

CUDA enabled? OK! I'll look into that!
Thanks

nVidia 560 GTX 2Gb Video Card
This is my video card, not on the CUDA list that I can see.
Best then if I disable GPU acceleration?

Never mind, guess the 5 series is OK for now, just not optimal, right?

The only 560 I see in the nVidia line is the GeForce GTX 560M for laptops. But it's no slouch with 192 CUDA cores and a Compute Capability of 2.1.

I'm running a very new NVidia GTX-590. The new drivers came out for it a week ago and I'm seeing EXCELLENT results.

System: 3.4GHz i7-2600k CPU with 16 GB of RAM
Video: NVidia (ASUS) GTX-590

On an 1:20 HD (720p) project with some compositing, but pretty much two tracks of audio with a nested project for the main body (interviews), using magic bullet looks in the nested project, I get the following render results:

CPU only render: 2:09
GPU only render: 0:57
Automatic Render: 0:56

I have no idea why I get a one-second gain in auto, but whatever. The results speak for themselves: CUDA wins hands-down. And that's just for a small project. If I'm rendering some of the longer projects I've been working on (22 minute TV shorts) the time saving has already paid for itself. Fast CUDA cards like the Quadros or GTX-590 aren't cheap but they do perform, and Vegas is taking advantage of that performance.

ps: I did this test with the new 295.73 NVidia drivers (better results than with the 285.xx and it seems reasonably stable too).

What kind of price range we talking for the NVidia-GTX 590?

Stringer wrote on 2/26/2012, 1:01 PM

The GTX 590 is hard to find.. $600 and up if you can find one..

If you find one, you will probably need a good 1000w power supply to go with it..
A 590 is two GTX 580 GPU's on one card ..

You will see good GPU encoding performance with a GTX 460 from ~$140, and better as you go up to a GTX 580, in the $460 range... The GTX 560Ti at around $200 is a good middle ground..

Keep in mind, you will only get the benefits of GPU encoding with HD ..

I have a 1200w power supply.
Well at the moment that's out of the budget.LOL!
I like the i7 but I have a Crosshair IV gaming Motherboard so right now I'm kinda stuck with AMD
