OpenCL vs denoiseprofile

[temperdu]

Bonjour,

Convaincu par DT sous Windows, j'ai migré sous Linux (Mint 18.3). Sur les conseils de membres, j'ai même acheté une carte graphique Nvidia au passage, juste pour DT. Mais je ne le trouvais pas aussi rapide que sous Windows.  Ma CG est une GeForce GTX 1060 3GB et OpenCL a l'air installé.

En lançant DT dans un terminal am moyen de darktable -d opencl, j'obtiens en effet les erreurs suivantes à chaque fois que j'exporte une photo

Code :

[pixelpipe_process] [export] using device 0

Il n'y a que denoiseprofile qui a l'air concerné. Comme indiqué ici https://www.darktable.org/2012/03/darktable-and-opencl/, j'ai augmenté opencl_memory_headroom pour le porter à 512. Pour info, avant d'arriver à cette erreur, au lancement, j'ai :

Est-ce qu'il y a quelques chose à faire pour avoir un DT tout rapide ?

EDIT

Je suis débile ! En augmentant opencl_memory_headroom dans darktablerc jusque 1024, j'arrive finalement à

Code :

[pixelpipe_process] [export] using device 0
[default_process_tiling_cl_ptp] use tiling on module 'denoiseprofile' for image with full size 5342 x 3688
[default_process_tiling_cl_ptp] (2 x 1) tiles with max dimensions 4204 x 3688 and overlap 32
[default_process_tiling_cl_ptp] tile (0, 0) with 4204 x 3688 at origin [0, 0]
[default_process_tiling_cl_ptp] tile (1, 0) with 1202 x 3688 at origin [4140, 0]

L'augmentation est peut-être rendue nécessaire par le fait que j'utilse un écran 4K.

Pour poser une question quant même : quels paramètres me conseilleriez vous dans "fonctionnement" pour ces histoires de tuiles, ainsi que les autres paramètres impliquant la mémoire ?

• Ma CG a 3GB de mémoire
  
• En RAM, le PC a 16GB
