Flou d'objectif très lent et quasi inutilisable

Bonjour,

Est-ce normal que la fonction "Flou d'objectif" soir toujours aussi lente qu'en phase béta et quasi inutilisable?

Et c'est encore pire si le masquage de la profondeur de champ est actif. Il faut plusieurs minutes avant d'avoir le résultat et le moindre changement est pénible. Et en plus un fosi la fonction activée pour 1 photo, c'est tout lightroom qui devient quasi inutilisable sauf à le fermer et le relancer.

So, yes, that GPU is probably not going to support AI in LrC, as that notice states :

"Votre système prend automatiquement en charge l'accélération limitée."

"Your system automatically supports limited acceleration."

Is this a desktop computer, that GPU would indicate it was, as a Laptop would have a different GPU built for laptops.

You may want to consider replacing that GPU. Their are several GPU specifications to look at when selecting a replacement. One that may cause future issues is the amount of VRAM. Some Adobe documents might lead you to think 4GB is enough, it is not, think at least 8 GB. And as you cannot add VRAM later, consider even more than 8GB. Adobe also mentions GPU Compute Benchmark score of 2000 or better. You may want to search the Internet on recommendations.

A second issue is your limit on Adobe Camera RAW CACHE. Currently set at the default of 5 GB. Even Adobe states that is too small and to increase that to at least 20 GB

Go to the 'Help - System Info' menu to check the version of Lightroom Classic. I believe the mask generation is done by the GPU, so check for updates of your GPU drivers.
