no GPU acceleration with GTX-570 in SVP 11
GPU acceleration appear to have no effect on preview frames rates and rendering times in SVP 11, with a GeForce GTX-570, driver 285.62, on an 8-core HP xw8400 system with Windows 7 Pro 64-bit and 8GB RAM.
The card does show up in the “Video acceleration of video processing” in “Video” preferences tab. Whether it is selected, or is off, the preview frames rates and rendering times are the same. Tried changing the preview quality, window size (i.e. no scaling), changing the project – nothing helps.
Anyone else experiencing this?
The footage is 720p60 from Sony EX-1.
Sony tech support’s responses are confusing and mystifying. To my client’s question, why he is not seeing any effect from GPU acceleration, their response was:
“Preview performance enhancement requires an OpenCL CUDA-enabled GPU and driver 270.xx or later with a GeForce GTX 4xx Series or higher GPU (or driver 285.62 or later with a GeForce GT 2xx Series or higher GPU).”
My client asks then: “This doesn’t answer my question. My card meets these requirements. The problem is that I’m not getting the advertised results. My note to you stated that there was no difference in performance with the card or without it.”
Sony’s response:
“OpenGL and OpenCL are not the same standard. Vegas requires the following in order for the card to be supported.
OpenCL CUDA-enabled GPU and driver 270.xx or later with a GeForce GTX 4xx Series or higher GPU (or driver 285.62 or later with a GeForce GT 2xx Series or higher GPU).”
This is utterly mystifying to me: the client said nothing about OpenCL or OpenGL to warrant Sony’s response. Also, not only the system and the card meet the requirements, Sony actually uses the GTX-570 as an example of GPU acceleration in their benchmarks.
Any ideas appreciated.

My guess is that SCS are attempting to inform people of the requirements needed for success. Why not ask them directly? IMO, asking here, is only going to add a further layer of confusion.

Not sure I understand your response. Whom would you like me to ask directly, and what?
We did ask Sony tech support directly; they have been of no help thus far.
Asking here, I am trying to see if anyone else has or had a similar problem, and if there is a solution.
Why does it add “a further layer of confusion”?

[Alex Gerulaitis] ” 8-core HP xw8400 system with Windows 7 Pro 64-bit and 8GB RAM”
Most users are running quad-core or less and can benefit from GPU acceleration. I have seen some users with 8 and 12-core systems that do not see any improvement. The reason is simple – your processor power exceeds what acceleration that GPU assist can provide.

Indeed, that is mostly the case Stephen.
The sad thing is that most editors who arent tech

Certainly not the case here given jerky playback even on basic 720p60 H.264 footage – and especially bad on simple effects and transitions which are supposed to play back in real time with GA (GPU accel).
Plus the system is not exactly new and is slower than most of today’s i5- and i7-based machines, has slower memory, etc.
So the GA was supposed to be quite a boost and it isn’t.
In other words, I can assure you that the GA here is not working – not sure why yet.

I sure have Matt: the card (we are using) is EVGA GTX-570 and all the requirements on that page are met. So at the moment, no clue why it’s not behaving.

I looked at the specs for the HP XW8400, and here’s what I found::
64-Bit Quad-Core Intel® Xeon® Processor 5300 Sequence (8 MB L2 cache) or Dual-Core Intel® Xeon® Processor 5100 Sequence (4 MB L2 cache)
1066 & 1333 MHz Front Side Bus support
4-channel 667 MHz FB-DIMM memory subsystem
Up to 32 GB memory capacityMy mistake in assuming that an 8-core PC would be a screamer.
Well, you do have 8-cores, but only 1Gb of RAM per core and only a 1.3 GHz FSB. Hardly a screamer. More of a whimper.
The minimum hardware spec for Vegas is a 2GHz processor, and in general, you should have at least 2Gb of RAM per core.
I suspect that even if the GPU is running wide open, your PC is still slow enough to be the bottleneck.

You’re saying that the system is too slow for any GPU acceleration to happen?
Somehow I don’t believe that. It’s not exactly an IBM PC AT after all. The GA does happen very nicely on a similarly equipped xw8400, on Adobe Premiere Pro CS5, with a very, very noticeable boost in fps and rendering speeds.

Just curious Stephen… his system is Xeon 5300.. so that could be up to 3ghz quad core processors, but is 1.33 ghz a slow FSB? RAM seems a bit light on, but with 8 cores chugging away surely it shouldn’t be a dog. Am I missing something here?
