is it possible to tap into the GPU via OpenCL to speed up the displaying images, files are getting bigger and bigger, when you load multiple images into qimage (let's say from Fuji 100s or Sony 7rv) it takes time to move from one image to another in the editor or when you try to crop
No. That's more suited for video and 3D modeling. I presume you are talking about raw photos since those have to be developed and take more time: those are not suited for GPU processing.
