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

Lightroom uses "smart previews" to speed up functionality, especially when working over a network.  Instead of editing the actual RAW file, it seems that a compressed version is stored locally and you perform edits on with the compressed file.

 

Canon's DPP takes no similar shortcuts.  Comparing DPP, which has to load the entire file across a network, to Lightromm, which loads a compressed local file, is comparing apples to oranges in some ways.  Is LR more efficient?  Yes.  My DPP process about six 25MB files RAW to JPEG per minute.

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

Yes, I totally agreed with yours to say and let's go back to beginning of my point:- 1. I really want Canon's to re-considerate about the software capabilities to support more than Nvidia display card coding on market in order to increase the usability with DPP for different type of the display card at least to support two larges of display card company (AMD Radeon / Nvidia GForce). Better to know this is end-to-end solution to add value on Canon's own camera products. 2. Increase processing performance to convert RAW file to JPEG. ( I don't want to explain anymore in details why to slow and everyone should know that in this topic. ) Other than that, I have no comment at this moment on this software in terms of functions / features and I like to use because it can simplify the work flow from time-to-time for processing thousands of thousands photo at rush moment. I have to say as a end-users written this words, the main point is we wish more efficiency and professional tools provided from Canon. As Fans, the loyally of the product.

All they have to do on the Mac is support OpenCL and it will automatically use any GPU on the system. That's what Lightroom, Photoshop, and virtually all other GPU/CPU intensive applications on macOS do. AFAIK, DPP is the only one to exclusively use CUDA (with OpenCL, CUDA is supported as well). It's a ridiculous decision. All the new high end iMacs, for example, including the scary new iMac Pro, use AMD GPUs, and they scream. Yet they are useless in DPP.

 

The application is a port from Windows and doens't leverage any Mac specific performance technologies. When apps do, it makes a huge difference. You can easily find videos [Removed 3rd party link per Forum Guidelines.] of lowly MacBooks absolutely smoking top of the line workstation PCs with significantly greater specs rednering the same 4K videos. The MacBooks use FinalCut Pro X, which naturally utilizes all the latest macOS performance APIs, against Adobe Premier on the PCs. It's the same reason Affinity Photo and Pixelmator are so **bleep** fast on the Mac compared to crossplatorm apps like Photoshop (Affinity is now cross platform, but was developed for macOS).

 

I can't say if I am or am not running macOS High Sierra, but hypothetically, let's just say WOW. Sadly, I doubt DPP will leverage any of the new APIs like Metal 2 or improved OpenCL. By accident it will get to use APFS, but only because it has no choice. **sigh**

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

I have Windows 10, Pentium 3Ghz, 4 GB RAM, not a super fast machine. I recently upgraded to DPP4 and was underwhelmed with how slow it was. Separately, I purchased a Nvidia GT 1030 card to support a 4k screen. I just recently noticed the option in DPP4 to turn on hardware acceleration since I now have the Nvidia card. I will just say that it made a huge difference on my machine. I don't process a ton of photos, but now with the hardware acceleration, it takes a lot less time.

 

Note that I'm processing RAW files from older cameras that are only 12 MP.

Exactly.  Having a separate graphics CPU and RAM makes a huge difference.  Thanks, for posting that tidbit of info.
