Thank you for this hint. I increased the value of opencl_memory_headroom until it starts tiling. No changes in performance at all. Maybe there is something else wrong with my system settings. Would be interessting if somebody else will get faster process times. Here is the RAW with the sidecarfile for testing: http://homepage.boku.ac.at/kanzian/dl/IMGP10191.zip Christian > Am 06.10.2013 um 03:12 schrieb Jack Bowling <[email protected]>: > > Similar setup here as with Christian but with a bit older video card: > > > > [opencl_init] device 0 `GeForce GT 630' has sm_20 support. > > [opencl_init] device 0 `GeForce GT 630' supports image sizes of 32768 x > > 32768 > > [opencl_init] device 0 `GeForce GT 630' allows GPU memory allocations of > > up to 511MB > > [opencl_init] device 0: GeForce GT 630 > > > > GLOBAL_MEM_SIZE: 2047MB > > MAX_WORK_GROUP_SIZE: 1024 > > MAX_WORK_ITEM_DIMENSIONS: 3 > > MAX_WORK_ITEM_SIZES: [ 1024 1024 64 ] > > DRIVER_VERSION: 304.88 > > DEVICE_VERSION: OpenCL 1.1 CUDA > > > > Note the older driver version being used. > > > > I also shoot Pentax (K5IIs in this case) and work with DNG files when > > doing astrophotography due to DeepSkyStacker not being able to handle > > PEF files.
