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

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.

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

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



- 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.
