Re: [darktable-dev] Darktable + Cloud-computing

[Steven Adler]

My PC is more than capable of processing photos and from what I've seen of
v2.3, the new GPU support in Darktable makes processing much much faster.
Cloud based GPU support would be great for advanced AI algorithms for
things like auto background replacement.  But still GPUs are advancing
rapidly and I doubt we will need cloud GPU augmentation for some years.

Danke.  Ich kann Deutsche lesen, but most people probably can’t and 
instructions in English might be more popular.

Best,
