Big difference between OpenCL and NoOpenCL processing in output picture jpg size (quality)
OpenCL output is more noisy:
darktable-cli RAW_NIKON1_V1.NEF RAW_NIKON1_V1_cli_perf_opencl.jpg --core -d perf opencl
darktable-cli RAW_NIKON1_V1.NEF RAW_NIKON1_V1_cli_perf.jpg --core -d perf --disable-opencl
Pictures and xmp are in the attachment.

#2 Updated by Ulrich Pegelow over 2 years ago
- % Done changed from 10 to 90
- Target version set to Candidate for next patch release
- Status changed from Confirmed to Fixed: To be cherry-picked
Reason has been a couple of silly bugs which are hopefully fixed now in master. Please check and report back. The fix should find its way into 2.2.4.
