after many years DPP solved !!

[mangurian]

I have always found DPP completely unusable.....Today, I discovered that my Nvidia software never recognized DPP.

I had the app scan for programs....still did not find DPP.
I added it manually.......now DPP smooth as silk.

This is very good news!  Can you share a bit more that might be of use to others ?  Windows 11?  Nvidia primary or secondary card?  You "added it manually" using the Nvidia Control Panel or ???

Yes there are others that would also like to know how you did it.

Could you add more info?

What Nvidia software? I have an Nvidia 1050Ti card in my PC for close to 10 years. Never had an issue using DPP and did not have any Nvidia software on my PC other than the Nvidia driver.

OK -some details.  I am running Windows 11.  I have an Nvidia 3060 graphics board.  Not the latest, but not bad.
NVIDIA has an app that scans your machine to add any apps it can optimize.  I recently found that several of my apps were "missed" by the scan.  I added them.  Two programs that had been unusable, are now super-fast.
They are Canon's DPP and DaVinci Resolve. Here's how you add them.  Open the Nvidia app and:

Thank you!

When you go into task manager, what is it showing for GPU activity for DPP?  I have always added DPP to the Nvidia control app, both the original and now with the more capable updated Nvidia app.  But DPP never really uses the GPU capabilities.

DPP is fast on the machine I am using (HP Z8 G5 with twin 28 core Xeon processors with 256 GB per CPU) and it has a pair of Nvida Ada 4000 series workstation cards with 6,144 Cuda cores and 20 GB DDR6 memory per card but no GPU usage by DPP.  Other programs I frequently use make good use of the Nvidia GPU resources (i.e. Matlab, Cyberlink Power Director) but not DPP.

More responsive is always better so if DPP is actually capable of making good use of Nvidia GPU capabilities but isn't doing so then I will dig deeper into it with my configuration. Processing of a high ISO CR3 RAW file into JPG takes 6 to 7 seconds, during this time CPU utilization briefly peaks at 10 to 11% for under a second but is in the single digit range for most of the processing time and GPU utilization by DPP never comes off 0.  The older CR2 files are faster, around 2 seconds for RAW to JPG with CPU utilization staying under 5% peak.

RAW file storage and output files are both on HP "Z drives" which are extremely fast SSDs that sit directly on the processor bus so file access time doesn't create any bottleneck.  

I really wish Canon would either farm DPP out or hire a consultant from a software firm to do a proper deep rewrite of DPP.  It has a lot of nice features but if you compared it to Canon's extensive line of cameras, instead of a 1 series it is an entry level "point and shoot" with some serious user interface issues.

Mangurian, Thank you for sharing your experiences with DPP.
