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

[raviballa]

I would love to continue to use DPP for its color output. But, where I am struggling with is its slowness to process RAW files. Loading of the RAW files is slow and I cannot tell when my minor corrections are applied to the image (there is no indication of DPP processing my adjustments). The 'Quick Check' of images is good though, without any lag.

Any suggestions?

Hi Peter,

Thank you for posting.

For the installation of Digital Photo Professional (DPP), we require a minimum of 2 GB and recommend 4 GB, or more. Since your computer indicates that 5.4 GB is being used, DPP is using all it can.

Does anyone know that below meaning just released from Canon's of Hong Kong for DPP 4.5.20 :-

Caution

- The recipes in Digital Photo Professional 4-series cannot be used interchangeably with the recipes in Digital Photo Professional 1 through Digital Photo Professional 3.
- Digital Photo Professional 4-series and Digital Photo Professional 3.15 can be simultaneously installed to one computer.
- Improved the display speed by using a graphics processor (GPU) to process images for preview. 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.

As result, means that if user have Mac machine with ATI chips set will not support GPU processing to speed up image preview performance?!

Thank you.

I've been using DPP3.x for a long time now and everything was working great. I upgraded to DPP4 and it eats memory like crazy. I have a Ryzen7 8 Core CPU with 32GB of RAM. Windows 10 64bit. SSD drive. The works. 

Any advice on how to rectify this? Seems like a memory leak. 

The memory consumption seems directly related to the number of photos in the active working folder. For example this folder has 80 images in it and consumes 99% of the RAM. I can opn a folder with 5 images and it consumes 7% or so.

Current version of DPP4 is 4.6.10.0

Using a separate graphics card with its' own video memory makes all the difference in the world.

 Nice piece of detective work! Thanks for posting this. I hadn't picked up on the relationship between the sluggishness and the large number of files in the active folder. What can make working with DPP4 so frustrating is that occasionally it runs up to speed but then the next time it will be bog slow. And it's not unusual for me to be working out of a folder with 50 or 100 files. Maybe rearranging things into some smaller subfolders would be a good  workaround for the time being.

I'm working strictly with the on board video on my Win7 Ultimate machine, so I think i'll be looking into adding a seperate graphics card of some sort. I'm assuming that it won't need to be any kind of an upscale gaming video card, maybe with 1 or 2 GB of its own RAM? Wonder if there's any other reconfiguring required...

I recently bought a gaming laptop because it was cheaper than a workstation laptop.  It has an i7 w/8 CPUs, 16 GB of system RAM and 4 GB on an NVIDIA graphics card.  When I run DPP4, it runs as fast as DPP3 did on my old Windows 7 machine, if not faster when it comes to batch processing.

I can start editing a photo after 2-3 seconds, instead of 20-30 seconds of watching the little spinning icon as the image is loaded.  My old DPP3 machine could batch process 20-30MB RAW files at about one per minute.  The gaming laptop can do about six per minute.  

I've run DPP4 on another laptop with an i3 and 8GB of RAM, and it crawls.  You can configure which applications use the graphics card.  Enabling DPP4 to use the graphics card seems to make it lightning fast.  Apparently, you cannot use a budget priced laptop, or even a low to medium performance laptop, with DPP4.  But, you don't need to buy the most expensive machine, either.  I bought a Dell on sale for roughly $1000.

Yes, I have the same problem. DPP (4.6.10) is virtually unusable with its current performance. I've been going back and forth with the Canon devs, and as of now they have no fix or explanation other than to admit "there is definitely something going on". 

I just did a commercial shoot where the workers were wearing very bright safety orange shirts. The color renders terribly in Lightroom, surprisingly well in macOS Photos, okay in DxO, but nearly perfect in DPP. Naturally, I wanted to handle production of this project in DPP, but I just can't do it.

It takes, on average, 20 seconds for a 5D Mark IV RAW file to load once I press "Edit Image." Once there, most of the editing is okay if not great, but selecting the dust/stamp tab takes another 25 seconds to load. Oh, and forget about trying to manually adjust image rotation/angle. It's so jerky it's unusable. I have to randomly enter numbers until I hit on just the right angle adjustment. Oh, and if you spend too much time editing the image, it will stop updating the preview with your adjustments, like it's run out of cache or memory. At that point, I can't even load a before and after preview. 

I'm running on pretty high end machine. A MacBook Pro (Retina, 15-inch, Mid 2014) with 2.5 GHz quad-core i7, 16 GB of RAM, and a 512 GB SSD along with the discrete NVIDIA GeForce GT750M with 2 GB of VRAM. I've tried DPP with "use graphics processor for image processing" enabled and disabled and, it if helps, it's so minimal I don't notice much of a difference.

Processor intensive applications like FinalCut Pro X, Photoshop, Lightroom, DxO and Photos run flawlessly on my MBP. DPP is the first application I've had serious performance issues with in years.

I put together a screen video for Canon showing the performance, so there is no question about my interpretation of the issue. Performance is abysmal. Restarts, reinstalls, and even trying an earlier version (they wanted me to try 4.5.20) have made no difference in terms of performance. DPP simply can't handle the 30 megapixel RAW images out of the 5D Mark IV. It's a shame, because in certain instances, nothing can touch DPP for color.

Point the developers to this thread so that they know it is a more general problem and not specific to Macs.

@KBeat, you nailed it on the head. Thanks for the detailed description. I have tried everything you did as well. As you said, DPP has the best colors in RAW image processing. If only they could improve the performance, this woud be a great product.
