I have another PC system with a Radeon HD 4800. I am curious about this issue, so I am going to install PD 10 on it and do the same experiment. I don't expect great results, but just the same I would be interested also if there is any difference. I have managed to create some extra time this morning, so I am going to do it now !!!
Thank you. Please check without preview.

I think the short test is misleading, I did a 59 minute test and this is the result.
With hardware encoding enabled it took 17 min 36 seconds,
with hardware encoding NOT enabled it took 36 min 14 seconds.
About 2 x which looks better. Attached are 2 screen capture images. enabled and NOT-enabled, showing CPU and GPU usage.
If the preview was disabled during production, then obviously GPU decrease the production time. But why in my case it doesn't work?

To enable/disable I check or uncheck the "use Hardware acceleration " option.
Thank you kingsmeadow.You have very nice setup.
In my case, it doesn't matter if "hardware acceleration" in the preferences, in on or off (I mean the "Enable AMD Accelerated Parallel Processing technology ..."+ "Enable hardware decoding" are enabled or disabled. In both cases, the "Fast video rendering technology" remain enabled. I even can't disable it from the production window. It is all the time enabled.

I just did a very simple test with and without GPU enabled. The "with" test took 18 seconds and the "without" test took 44 seconds.
I did not use enable preview to make it fair. I was using AVC as the test profile and AVC-HD 1920 X 1080 as the format.
in this case I think it's fair to say that it does make a difference. i think also it may depend on the hardware and the format chosen.
I am happy to hear that! This is a huge difference (2,4 faster). Please tell us some details:
- Do you use PD 10?
- What kind of GPU and CPU do you use?
- What kind of settings do you have in the Preferences/Hardware acceleration?
- How did you disable/enable GPU (take out from the computer or change it)?
- Did you measure the CPU and GPU load in both cases?
Please give us a feedback. Thank you.

I am very curious, if somebody obtained a significant higher processing speed, on account of GPU. I would like to know if these improvement is possible, because in my case is more cheaper to upgrade the GPU in place of CPU.
Until somebody will show me the facts, for the moment, I suppose there are a lot of marketing regarding the hardware acceleration on behalf of GPU.

Hello,
I am trying to speed the production process in PD10, taking in account the following features:
- OpenCL to harness GPU power for greatly improved video effect speed;
- Hardware video encoder enabled.
I mention that I use a system with AMD Athlon 64 X2 5200+ and a GPU AMD Radeon 6850 (1G DDR5), so my computer supports hardware acceleration, since I have graphics card that supports AMD Accelerated Parallel Processing.
I am not able to see any improvement in the production speed. If I use the onboad graphic card or use the dedicated GPU card (AMD Radeon 6850) there is no difference, even that in the second case I see the "Hardware video encoder"enabled.
I processed a 3:50 minutes video, with 720p HD movies, some pictures, using transitions and some Pip objects in 4:30 minutes. The CPU Usage is 90% - 100% and the GPU usages varies between 0% - 10%, but most of the time is 0%.
In case I enable preview during production, I can see a 53% usage of GPU and 90% - 100% CPU usage.
So, in my case conclusions are:
- GPU doesn't accelerate the production process. I got the same time if I produce with a poor onboard GPU (ATI 3200) or if I produce with a middle range GPU AMD Radeon 6850;
- GPU does help, only if I "enable preview during production", but this thing doesn't decrease the producing time. Only helps to be able to preview the movie during the production.
- I suppose that only a better CPU, will increase the processing speed.
- It is possible that in some certain conditions (many transitions, and Pip obsjects), to see a resonable difference. If there are only a few Pip objects and few transitions, there are no difference with special GPU or without.
Special GPU means all these new sophisticated technology implemented in the latest GPU's:
- OpenGL® 4.1;
- AMD App Acceleration
- Avivo™ HD
- a.s.o.
