I have a Nvidia GTX560 display card, I cannot see CUDA acceleration, only OpenCL in hardware acceleration. Please let me know how to enable CUDA for my PD15. Thanks.

Per Jeff, above:

"That is the correct operational mode, your CUDA note PC is not correct. If you reinstall Nvidia drivers on the CUDA note PC it will then offer the correct OpenCL note." Regards,

Jpong2226 – It seem that you have an earlier Fermi and not the Kepler architecture cards discussed here. It may be possible for you to enable cuda if you install 5 year old nvidia graphics drivers which may also enable hardware encoding for your card.

You probably need to start a new topic post to get help and information.

I don't believe so, one will get OpenCL Fx acceleration anytime the GPU supports OpenCL capability. If you want true CUDA Fx acceleration vs OpenCL accelerated support in PD, one needs a GPU that does not support OpenCL, say a Nvidia 9800 GT for a desktop. OpenCL or CUDA acceleration for Fx totatly different than hardware encoding.

That's correct.

HOWEVER, since you card is a Fermi generation card, it doesn't have the hardware needed for hardware accelerated NVENC encoding of the final product.

In the past I have written a post exactly for those generation GPU's - how to reactivate the CUDA encoding for them. This is different from the OpenCL/CUDA option in the main menu (that one applies only to FX's), and it is visible only at the "produce" stage. Don't know if will still work in PD15.

FYI, I tried testing with "enable OpenCL technology..." checked and unchecked, and saw no difference whatsoever with producing 1920x1080 60i 24Mbps M2TS source -> 1920x1080 30p 8.7Mbps (Fast Vid Render/HW Vid Encoder checked on Produce page). I'm using a Nvidia GTX1060 6MB card. In both cases the CPU load was identical, around 19%, and the GPU was at 97% "Video Engine Load". GPU load was 5%. No effects, single clip, 1Hr12Min, produce time 7 minutes (loving my new GTX1060!).

I did close and reopen Powerdirector in-between runs, btw.

That's normal - because you didn't use any (HW accelerated) effects.
That's the only case where that "OpenCL" tick mark does a difference.
What you have tested is the encoding ASIC in your video card. Totally separate from the GPU cores.

I get a bit lost in the GPU world but here is an interesting video on "GPU vs CPU Video Rendering and Video Editing"
