GPU acceleration (?)

lewist57 wrote on 1/27/2012, 9:24 PM
Build 521 apparently has recognized my ATI FirePro 7750 workstation video card (I think). The term "initializing GPU acceleration" appears in the initial splash screen, and now under the Options > Video > GPU acceleration tab there is something other than just "off". But what it lists is the CPU (an Amd quad core), and not the video card. Dumb question - for those users with GPU acceleration working, does it list your video card, or the main processor?

It lists my video card.

Lists my GTS 450 only.

Thanks for your replies, I guess it will remain a mystery for a while longer.

You may be expecting consistency in vain. There may be no basis for you to expect that the description is uniformly applied to all devices. It could simply be whatever the programmer at that moment decided to type in when adding the driver for that device. As long as it lists GPU acceleration why do you care what it calls it? The vastly more important question is, does it work?

Don't know much about the current AMD processors, but does yours have an integrated graphics subsystem?

No the mother board is a Tyan server board with two quad core CPUs, about four years old, not the recently introduced AMD combo processors. Video is an ATI Fire pro 7750 workstation card, 1G vram on board, running Win7 - x64 ultimate.

1) does it work - haven't run tests yet, will post results when I do.
2) why care? - I invested quite a bit of cash to buy my workstation card, and specifically waited to buy V11 (from 9, which had no problems) for the GPU acceleration. Since it is listing the CPU and not the GPU, I am assuming that it is not recognizing my $700 GPU, and therefore not "accelerating" at all. However, you are correct in that I need to confirm if there is any change with the feature on or off.

Simple render of 2 minutes of standard video with acceleration off takes 2:22, and my eight cores are loaded about 25%. With the acceleration on (remember it is reporting my AMD CPU, not the ATI GPU), the seme render takes 8:00, and all eight cores are loaded at 80%. Not what I expected.

If you take a look at Sony's section on GPU acceleration in VP 11, your FirePro is not listed but it's big brother, the V8800, is listed but it doesn't show that great an improvement compared to cheaper game cards like the GTX570 except for playback. That's where you should see more of an improvement in your case.

As for rendering speed, there are a lot of variables that can affect your rendering times: what format are you using? What kind of work are you requesting from your computer? If there are a lot of video transitions and effects that take advantage of GPU acceleration, you might see a bigger difference between the straight CPU times vs the CPU/GPU combo times.

If you don't mind, can you provide the link or direction to the GPU reference for the V8800? Thanks.

Thanks, I forgot about that page.

As of Valentine's Day 2012, build 521 and ATI version 8.911 video driver, VP11 still not recognizing video card.

Just for fun I rendered a short (1:20 min) standard definition clip to MPEG-2 (for DVD Arch). Took 40 seconds on VP09 and all eight cores were loaded to 75%+. Took 1:59 on exactly the same settings for VP11 (no GPU acceleration), with all eight cores only loaded to about 30%.

Latest 64 bit update, latest ATI driver (as of March 1st), GPU acceleration still lists either off or my CPU (not my GPU). Rendering times for "off" are 10x faster than the CPU option.
