I just noticed, the tiling is only happening for Jochen and not for you. In that case this option does not change a whole lot, because the memory is not a problem for you as far as I can see (only skimmed the log, so I might have missed something). You said you are usually using bigger files, how does the export look for those? > My starting value was 3,306 secs. So opencl_use_pinned_memory doesn't > change the speed a lot too. This is not too suprising, but good to test anyways. For big transfers, at least for older hardware, this can double the bandwidth, but darktable does not need seem to transfer enough data to take advantage of it.
