Hi,
I would like to share some of the notes I have put together for using
Filmic. Filmic V4 is very easy to use. Avoid making it unnecessarily
complicated. I rarely use the highlights reconstruction as bleaching
highlights should be avoided in the camera in the first place. I love
Filmic V4
Indeed Patrick,
the default in the current version is:
opencl_synch_cache=active module
The option I would advise to test for response time comfort during finetuning
in a 2nd pass is:
opencl_synch_cache=true.
That is if it does not compromise too hard overall response time. Which is ok

Here,
Lenovo Thinkpad P53, GPU Nvidia Quadro T2000
Darktable 3.2.1-3 (installed, not snap)
on Debian Sid
with the recent NVidia drivers, 450.80.02
and kernel 5.8 (OpenCL works) or with kernel 5.9 (Open CL doesn't work)
The difference with/without OpenCL is visible as soon as a raw image
Gian,
Good to hear that. And yes I expect that that XEON processor will surely help
(*).
GPU performance can be further boosted by optimization of the opencl settings
in file darktablerc. You can read about that in the darktable manual.
But possibly adequate parameters for a
Marc,
thank you very much for your warning!
As you see, the first step is done, and I can see a huge improvement in
browsing through the lighttable with the GTX 1650.
I was wondering too if it is worth to go to 4K, I wouldn't like to go
back to square one, performance wise.
Maybe
Gian-Luca, Just a little warning about purchasing a 4K display. You indeed will need a good GPU. But still there is (or are) module(s) that are fully cpu-bound. That’s the case with tone equaliser. Interactive response when zooming and panning in the darkroom may suffer from poor response time on
to the benefit of all readers, I would like to confirm that OpenCL works
in this environment:
* Ubuntu 20.04LTS
* Lenovo TS140
* Palix Nvidia GeForce GTX1650, 4GB
* Darktable 3.2.1 (installed via apt, NOT snap!)
