Re: Digital Photo Professional (DPP) 4.5.X is slow (performance)

No support for AMD GPU's? Only Nvidia? Each owns about half of the graphics market. Supprised.

More details on Canon Website. I have only Nvidia.

Re: Digital Photo Professional (DPP) 4.5.X is slow (performance)

If you can, post a link to the Canon site showing the upgrade information. I think I've already got this latest version installed and things are still sluggish on my Win7 desktop. I installed a used nVidia graphics card with 2gb of RAM and 240-some Cuda cores along with a bigger 750w power supply. But I was still unable to get DPP4 to recognize and access the GPU.

Canon specs call for a graphics card that has "Compute Capability 2.0 or higher". The older used card I installed only had Compute Capability 1.3 so I'm still looking for a decent price on a slightly newer, used nVidea GPU.

Here is the link:

I'm using Nvidia GTX1060. With new DPP version the speed improvement is significantly better.

It still doesn't work properly and freezes. I thought it might of been the hard drive I was pulling the photos from, but this actually happens after I swapped them out.

It might be necessary to look closer at the PC, but difficult to give the advice at the Forum. In my case I face real slown down while using DPP with large RAW files from EOS 5dmkIV. With DPP 4.9.20 I observed significant improvement.

Thanks for the link. I never think of checking the "overseas" Canon sites to see if they have info I hadn't found on the U.S. site. This seems to explain the improvements you might see more clearly than what I've seen so far from the Canon US site.

 

From your link...

Improved the display speed by using a graphics processor (GPU) to process images for preview in 64-bit OS (32-bit OS not supported).

 

For converting and saving, and printing, the conventional CPU processing is used.


To use this function, a GPU that has 1.0GB or more of built-in video memory and that supports CUDA (Compute Capability 2.0 or later) made by NVIDIA is required. In addition, the latest driver made by NVIDIA must be installed.


I think I suapected all along that this might be the case as far as a better GPU only improving image preview display time. Speeding up the actual image processing is still more dependant on things like the OS, CPU and RAM.

Why no support for AMD? That's half the PC universe.

The single biggest benefit of using a separate video graphics card comes from freeing up System RAM.  You are no longer forcing the main CPU to share System RAM with the video graphics hardware.  The speed improvements are more noticeable on slower CPUs than faster ones.
