Hi, I've felt that darktable has been rather slow for a while now, and when trying to figure out why I found out that even though I have OpenCL activated it's running demosaicing on the CPU. Running darktable with -d perf and opening an image gives this:
[dev_pixelpipe] took 0.000 secs (0.000 CPU) initing base buffer [full] [dev_pixelpipe] took 0.015 secs (0.013 CPU) processed `let's go float!' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.006 secs (-0.000 CPU) processed `white balance' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.006 secs (0.003 CPU) processed `highlight reconstruction' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.737 secs (3.467 CPU) processed `demosaic' on CPU, blended on CPU [full] [dev_pixelpipe] took 0.006 secs (0.007 CPU) processed `base curve ' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.003 secs (0.000 CPU) processed `input color profile' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.002 secs (0.003 CPU) processed `levels' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.004 secs (0.000 CPU) processed `sharpen ' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.004 secs (0.000 CPU) processed `output color profile ' on GPU, blended on GPU [full] [dev_pixelpipe] took 0.091 secs (0.007 CPU) processed `gamma' on CPU, blended on CPU [full] [dev_process_image] pixel pipeline processing took 0.874 secs (3.500 CPU) For some reason it's running everything on the GPU, except for demosaic and gamma which seem to take most of the time. I haven't touched the demosaic module (or any other module) in this case, so it's using the default PPG which I thought could use OpenCL. Or am I mistaken? -d opencl doesn't show any kind of errors, and even says that it's in fact loading several PPG kernels when starting darktable. This is with darktable built from git a couple of days ago, on ArchLinux x86_64. The GPU is a GeForce GTX 560 Ti using Nvidia 340.32 drivers. Deleting ~/.cache/darktable made no difference.
