J’essaie de me mettre à Darktable sur mon mac mais niveau réactivité ce n’est pas ça du tout alors que le mac est tout neuf et que tout est super fluide sur Lightroom et sur CaptureOne.
Voici un log de OpenCL lorsque je fais un rotate de l’image. Je dois slider et viser au pif puis attendre que la correction se fasse avant de voir le résultat et à nouveau y aller au pif et ainsi de suite. Ce n’est pas le seul module qui manque de réactivité.
Peut-être y-a-t’il un paramètre que je peux changer pour voir mes modifications presque en « live ».
Après à peine quelques minutes d’utilisation de Darktable le ventilateur se met au maximum…

Et MacOS étant aussi un Unix, il y a quand même un certain nombre de points communs.
