I checked and the DLO is off (DPP crashed when I turned it on and adjusted an image...).
I tried to find Canon support for DPP, but didn't succeed. Guess I could try contacting them anyway but "software support" or something like that would probably increase odds of getting a useful reply.
It would be really nice if Canon would come up with at least some suggestions as to how to get the best performance out of DPP. I wonder if there are software conflicts that occur under the radar, especially with background programs like anti-virus or anti-malware types of programs. Something that would try to fully scan an image file every time it's changed or something odd like that.
I don't know. I'm not unhappy with how it operates on my quad core desktop, nor on my i5 MBP. Although, I do most of my heavy processing on the desktop, I do have DPP on both. I like to use the laptop when I'm traveling to serve as a quick way to process images of needed, and as a sort of a backup storage device.
I wonder too if DPP tries to use the video processor or relies strictly on the main CPU. I know you can switch on or off the use of the video processor in LR. I don't see many options in DPP however.
I prefer converting my raw files to the adobe universal raw format so I've not used dp in years so no help. I switched to the universal raw format after a previous cataloging program didn't recognize my 40D raw files after upgrading to the 40D. It thought me a lesson go with universal formats.

Hi Jan,
That's very bad. sorry to hear it crashes on you.
I am not sure about your country, but here in the US if you have CPS membership you can call Canon CPS directly as opposed to going through the general Canon support. They are open 24 x 7. They will walk you through the steps needed to fix the issue. I remember several years ago I had an issue with DPP on my Mac. After easting my time on the internet looking for a solution, I just called them an we fixed it on the phone. It was a file corruption that was happening after Mac OS update.
It may ultimately be an issue with your Mac OS setup in which case you have to ask Apple for help, unfortunately you might have less luck if that's the case as Apple usually don't provide any support for software that's not their own.
The latest DPP 4.5 runs a bit faster than 4.4 on my Mac Pro. In particular the double pixel RAW processing is quite fast and much better than I thought it would be.

DPP does have the option to use GPU (ver 4.4 or later). It's located under preferences --> image processing 2
But if you have a Mac, DPP will not be able to use GPU as Apple does not have CUDA hardware anyway. thus the option will be greyed out....
On a PC it makes thing faster if you have a capable high-end GPU such as the latest Nvidia GTX series. I have used it with GTX1080.
DPP 4.50 crashes when started when used on a computer with an Nvidia M2000 board. Seems to work when used on an internal graphics. I really don't think Canon really wants to support DPP and just has it available as a placebo.

Unfortunately, on my PC, that option is greyed out for some reason. Perhaps only specific graphics cards/processors are supported. For the record, my PC has an AMD Radeon HD 7700 graphics card with 2 gig on board. It probably isn't close to high end.

ATI does not support CUDA which is an NVIDIA platform. NVIDIA GPU's are widely used and supported in the IT industry for computation so most companies go with CUDA.
Thanks, speedmaster20d. It's a little outside of my area of expertise.
Would changing graphics cards make a difference? Not that I would do that for DPP, especially when I have LR and it apparently DOES use the graphics processor (or at least lies about it).
This might bring up the logical question - how much of a role does the speed of a graphics card play in the processing of images in general?

For LR and Photoshop GPU doesn't really play a significant role, so getting a high-end card vs. what you have makes little difference and is not a good investment.
If you have a large 4K display like mine however a good GPU makes your overall experience a lot smoother.
Wow, AMD's OpenCL is supported by Adobe and it's not so insignificant that Canon should not offer it as an option, plenty of people use AMD cards, and their FireGL cards are very good easily comparable to Quadro cards.
