That’s great that you got your opencl working. You can try tweaking some things in your .config/darktablerc file as well. For me, by simple trial and error, I found that changing “opencl_number_event_handles” to 150 and “opencl_memory_headroom” to 400 works best for my hardware. The export times and the “working” times when applying a new module are way faster than without the opencl active.
