Sur quel matériel installer DT ?

[Cobert]

Bonjour,
Je partage la pertinence d'openCL avec une carte graphique qui le supporte sur les temps de traitement.
30 secondes ou plus à l'export  avec cette config, c'est quand même bizarre?
En lançant darktable -d perf on peut peut-être voir quels modules prends du temps.

exemple chez moi :
