GPU accellerated rendering – No difference if unchecked

[Alex Udell]

I’m not sure, but Ithink you have to use this in concert with the specific GPU FX…

First off…Its GPU accelerated playback and rendering I have run numerous tests to see if this works and it does. Infact, Steven ran a few tests while we were on the phone and he will give you the same answer that I did.

[BogeyB] “Another issue: Even if the GPU accelleration is activated there is always the red “needs to be rendered”-bar above the timeline.”

GPU accelerated playback does not mean that you do not have to render. You have to render whether the option is turned on or not.

[BogeyB] “Has anyone an idea how to configure the System/Drivers/PPro 2 to know the true promise of GPU accellerated rendering???”

I have the 6800GO (mobile version) and it works on my end. Can you run a few tests and provide us with test results, in terms of time taken when GPU Accelerated Playback is activated and when it’s de-activated?

Thanks for your posts…

OK, Here are some rendertimes:

a) Two 30 second DV Clips with a 30 second cross dissolve between them: Rendering-time: 13 seconds whether checked GPU accellerated rendering or not.

b) a one minute DV clip with the quick color corrector needs 33 seconds to render whether activated GPU rendering or not

In both cases, rendering times are exactly the same, and – what i wonder about – in both cases rendering time is less than the original clip-lenght. So my machine is rendering “faster than realtime”, but playing back directly from the timeline the preview quality is reduced (if set to auto), or the playback is stuttering if preview quality is set to “high”.

Any ideas, guys??
