sets level for smoothing of brush strokes. stronger smoothing leads to less nodes and easier editing but with lower control of accuracy.
cache_color_managed bool true color manage cached thumbnails
if enabled, cached thumbnails will be color managed so that lighttable and filmstrip can show correct colors. otherwise the results may look wrong once the display profile gets changed.
cache_disk_backend bool true enable disk backend for thumbnail cache
if enabled, write thumbnails to disk (.cache/darktable/) when evicted from the memory cache. note that this can take a lot of memory (several gigabytes for 20k images) and will never delete cached thumbnails again. it's safe though to delete these manually, if you want. light table performance will be increased greatly when browsing a lot. to generate all thumbnails of your entire collection offline, run 'darktable-generate-cache'.
cache_disk_backend_full bool false enable disk backend for full preview cache
if enabled, write full preview to disk (.cache/darktable/) when evicted from the memory cache. note that this can take a lot of memory (several gigabytes for 20k images) and will never delete cached thumbnails again. it's safe though to delete these manually, if you want. light table performance will be increased greatly when zooming image in full preview mode.

database/create_snapshot enum
  • never
  • once a month
  • once a week
  • once a day
  • on close
 once a week create database snapshot
database snapshots are created right before closing darktable. options allow you to choose how often to make snapshots:\nnever - simply don't do snapshots. that way the only snapshots done are mandatory version-upgrade snapshots\nonce a month - create snapshot if a month has passed since last snapshot\nonce a week - create snapshot if 7 days had passed since last snapshot\nonce a day - create snapshot if over 24h passed since last snapshot\non close - create snapshot every time darktable is closed

affects only the thumbnail cache used for quick startup.
host_memory_limit int 1500 host memory limit (in MB) for tiling
this variable controls the maximum amount of memory (in MB) a module may use during image processing. lower values will force memory hungry modules to process image with increasing number of tiles. setting this to 0 will omit any limit. values below 500 will be treated as 500 (needs a restart).
lighttable/ui/expose_statuses bool false always show thumbnail overlays
show overlays (rating stars, 'edited' mark, etc) for all thumbnails in file manager, not only hovered one
lighttable/ui/preview/bottom_visible bool true show bottom panel in preview mode

this option toggles the behavior of shift clicking in lighttable mode
max_panel_height int 400 maximum width of the side panels in pixels
(needs a restart)
max_panel_width int 500 maximum width of the side panels in pixels
(needs a restart)
maximum_number_tiles int 10000 assumed maximum sane number of tiles
if during tiling this number is exceeded darktable assumes that tiling is not possible and falls back to untiled processing - with all system memory limits taking full effect. in case you want to process huge images you may want to increase this number.
metadata/resolution int 300 DPI value for exported files
min_panel_height int 64 minimum width of the side panels in pixels
(needs a restart)
min_panel_width int 150 minimum width of the side panels in pixels
(needs a restart)
modules/default_presets_first bool true sort built-in presets first
whether to show built-in presets first before user's presets in presets menu.
omit_tag_hierarchy bool false omit hierarchy in simple tag lists
when creating XMP file the hierarchical tags are also added as a simple list of non-hierarchical ones to make them visible to some other programs. when this option is checked darktable will only include their last part and ignore the rest. so 'foo|bar|baz' will only add 'baz'.
opencl bool true activate OpenCL support
if found, use OpenCL runtime on your system for improved processing speed. can be switched on and off at any time.
opencl_async_pixelpipe bool false run OpenCL pixelpipe asynchronously
if set to TRUE OpenCL pixelpipe will not be synchronized on a per-module basis. this can improve pixelpipe latency. however, potential OpenCL errors would be detected late; in such a case the complete pixelpipe needs to be reprocessed instead of only a single module. export pixelpipe will always be run synchronously.
opencl_avoid_atomics bool false do not run OpenCL kernels which require atomic operations
if set to TRUE darktable will not use OpenCL kernels which contain atomic operations (example bilateral). pixelpipe processing will be done on CPU for the affected modules. useful if your OpenCL implementation freezes/crashes on atomics or if they are processed with a bad performance.
opencl_checksum string checksum representing the setup of opencl devices on this computer
darktable re-checks the performance benchmarks of your system in case your setup has changed, which is indicated by a change versus the stored checksum in this config variable; darktable de-activates opencl if the GPU benchmark lies below the one of the CPU; initial value is the empty string; set to OFF if you want to deactivate any automatic checks and prefer to do all configurations manually.
opencl_device_priority string */!0,*/*/*/!0,* priority of OpenCL devices for each pixelpipe type
defines priorities on how (multiple) OpenCL devices are allocated to the different types of pixelpipe (full, preview, export, thumbnail, preview2). for more details visit our usermanual (needs a restart).
opencl_disable_drivers_blacklist bool false whether to allow some partial opencl implementations to be used or not
not all opencl implementations are fully-functional, there are at least two, which are not production-quality yet: pocl and beignet; therefore at this point in time, it is better to explicitly blacklist them by default. can be changed by setting this configuration option to TRUE (needs a restart).
opencl_library string system library with OpenCL runtime
OpenCL runtime library is normally detected automatically by darktable. if your OpenCL runtime is at an unusual place and cannot be detected, enter the full pathname here. leave empty for default behavior.
opencl_mandatory_timeout int 200 timeout period for locking mandatory opencl device
time period (in units of 5ms) after which we give up try-locking an opencl device for mandatory use. defaults to 200.
opencl_memory_headroom int 400 amount of OpenCL memory (in MB) which we assume as being reserved for the driver
this amount of memory (in MB) will be subtracted from total GPU memory in order to calculate the available OpenCL memory. too low values will lead to out-of-memory situations in OpenCL processing. too high values will lead to unnecessary tiling (needs a restart).
opencl_memory_requirement int 768 minimum amount of GPU memory (MB) required to activate OpenCL
OpenCL will only be activated if your graphics card has at least this amount of memory. reducing the value will allow cards with less GPU memory to be used - but at the risk of lower system stability and occasional crashes. values below 200 will be treated as 200.
opencl_micro_nap int 1000 pause OpenCL processing for this number of microseconds from time to time
for slow GPUs this gives your graphics driver some time to breathe to do needed screen updates. can be left at zero for fast devices.
opencl_number_event_handles int 25 the number of OpenCL event handles darktable can use
a positive non-zero integer defines the number of event handles that darktable may have opened on a device. a value of -1 does not pose any restrictions, bearing the risk of hitting the device's resource limits. a value of zero completely prevents the use of event handles.
opencl_scheduling_profile enum
  • default
  • multiple GPUs
  • very fast GPU
 default OpenCL scheduling profile
defines how preview and full pixelpipe tasks are scheduled on OpenCL enabled systems. default - GPU processes full and CPU processes preview pipe (adaptable by config parameters); multiple GPUs - process both pixelpipes in parallel on two different GPUs; very fast GPU - process both pixelpipes sequentially on the GPU.
opencl_size_roundup int 16 round OpenCL work group sizes to a multiple of
in OpenCL processing round width/height of global work groups to a multiple of this value. reasonable values are powers of 2. this parameter can have high impact on OpenCL performance.
opencl_synch_cache enum
  • true
  • active module
  • false
 active module cache intermediate OpenCL output
active module (default) - cache the input to the currently focused module, which allows for faster response time when making multiple adjustments to that module (though the whole pipeline may need to be reprocessed when another module is changed); true - cache the output after each module, which may improve speed, as the whole pixelpipe won't be reprocessed on every parameter change, though will require more memory transfers from the GPU; false - do not sync the pixelpipe cache from OpenCL, which avoids memory transfers from GPUs fast enough to smoothly reprocess the whole pixelpipe.
opencl_use_cpu_devices bool false whether to make use of CPU OpenCL devices
typically darktable's hand-optimized CPU code is much faster than any OpenCL-on-CPU code; therefore CPUs are excluded from being used as OpenCL devices by default. can be changed by setting this configuration option to TRUE (needs a restart).
opencl_use_pinned_memory bool false whether to use pinned memory transfer during tiling
during tiling huge amounts of memory need to be transferred between host and device. for some OpenCL implementations direct memory transfers give a drastic performance penalty. this can often be avoided by using indirect transfers via pinned memory. other devices have more efficient direct memory transfer implementations. AMD seems to belong to the first group, nvidia to the second.
panel_scrollbars_always_visible bool true always show panels' scrollbars
defines whether the panel scrollbars should be always visible or activated only depending on the content. (need a restart)
performance_configuration_version_completed int 0 version of the last completed performance configuration
what was the last performance configuration which has been completed
pixelpipe_synchronization_timeout int 200 timeout period of pixelpipe synchronization
time period (in units of 5ms) after which synchronization of preview and full pixelpipe is assumed to have failed. set to zero to omit pixelpipe synchronization. defaults to 200.
