My budget is little, I have to stay within 150euros: I'm orientated to

If I look at the economical side, the 1050ti is a little more

The question is: what do you suggest me to buy? The RX560 or the

Looking at this mailing list I've seen that there is also the problem 
of the drivers for the GPUs. I can use the Open driver or the 
Proprietary one, simply I'll choose the faster/better of the two.


And last: is my linux distribution (Debian testing) problematic for

Why is this?

That's because the Intel graphics chips are not suited for high end
computations as NVIDIA/AMD ones are. Just forget about it.

so these GPUs are slower than using CPU?
OK, I got it - thanks.

This is awesome news!
Although I'm a Linux guy these days, I am the producer and co-host of a
photography podcast called Shutters Inc, and most of my listeners are on
Windoze.
I'll be giving this a shoutout on this week's podcast for sure!
Although I've been raving about dt ever since I found it 12 months ago,
I've only converted one listener (that I know of). This will probably see a
few more at least sample the product, and I would expect, a few of them
will stay. I know a lot of people are not happy about Adobe's continual
price gouging for a CC subscription. :)

[darktable-user] openCL to slow down darktable?

[Bernhard]

Hi,

I use a mini PC for travelling by motorhome - also for editing images 
with darktable.
Today I managed to activate openCL - but after that dt is so slow I 
cannot use it anymore.
Changing exposure has a delay of seconds until the GUI reacts - other 
modules I could not test really.


I then started my benchmark scipt which uses dt-cli on 6 sample-images 
to export them and report the time.

Here is what I got:

 so you see that denoising e. g. takes 3 times as long when openCL is 
ON, but also all the other modules take longer, downscaling at the end 
is slowed down by a factor of more than 8, sharpening by almost 10.

[darktable-user] darktable for Windows

[Tobias Ellinghaus]

Hello everyone,

as most of you probably noticed by now we have had quite some work done in the 
past months to port darktable to Windows. It's mostly due to Peter Budai that 
we are able to provide a first public preview of what we achieved so far. Find 
the disclaimer and a link to the installer on the pixls forum:

Basic support for that camera was added 28 Jul 2016.
1.6.9 was released on 15 Oct 2015

Anything older than 2.2.x is hopelessly old, unsupported, and should
not be used.
If you are using LTS distro / simply do not want to update, then that
is your problem.
