Hi Anton!
I am on really thin ice here – but according to your log file, you have two graphic devices, but only one (your Intel HD Graphics 4000) is checked. You need assistance from one of the devs @houz , who hopefully has a better answer than I have.
Good luck,
Claes in Lund, Sweden
PS: Why mix \ and / in the paths (see same log file)?
Hi Anton, I’d suggest to read this pretty comprehensive article on OpenCL and dt:
Reading your log it seems the problem is this line:
allows GPU memory allocations of up to 324MB
dt by default expects at least 768MB GPU memory to use OpenCL. Read the whole article, at the end you can find some further hints and tweaks, it might help you.
So, I run from command line (CMD from windows), not showing any log, errors
The Windows version of dt logs to the following place by default:
Windows 10:
C:\Users\[username]\AppData\Local\Microsoft\Windows\INetCache\darktable\darktable-log.txt
Windows 7:
C:\Users\[username]\AppData\Local\Microsoft\Windows\Temporary Internet Files\darktable\darktable-log.txt
Note to myself: this should be added to the FAQ
Yeah, You should add that to FAQ
So, i have logs, scripts are not compatible with new API.
version: darktable 2.4.0
start: 2017:12:31 14:31:02
LUA ERROR : …s\mrt89\AppData\Local\darktable/lua/Copy_Paste_MDATA.lua:26: Module Copy_Paste_MDATA is not compatible with API 5.0.0
edit:
Working now, I added check for API 5.0.0 and script working now
Thanks, just post a massage to @houz
Thanks! But when I reduced opencl_memory_requirement from 768 to 300, still get no luck…
Anton, which is your second graphic device (see above)?
My laptop has only one - intel hd4000. no other gpu…
Intel OpenCL is not supported IIRC
My experience with a Win10 laptop and an Intel HD Graphics 520 integrated card is, that OpenCL does work, although not with every version of the driver. The gain is modest and expendable, like 30 %, while, on the other hand, enabling OpenCL can harm the picture, at least in combination with some modules (like colour zones), when blown highlights can become black (also in the exported image).
(Un)luckily I am away from home and the laptop, but I will recheck this and try to make an useful report. It is a combination of hardware, dt version and driver version, so probably not easy to reproduce. In general, OpenCL should be disabled in this case, I believe.
On an old Win7 PC with a HD 7850 (2 GB) card, the difference is noticeable, like 3 : 1. No problems, big improvement.
Seem to be having an issue exporting with Windows 10, 8GB RAM, AMD A12 processor, AMD Radeon R7 Graphics. Only the top part of the image is exported and the bottom portion is black. Works OK on an older Intel i5 laptop. The XMP and jpg files are in bug 11903…not sure if it’s a bug, but seemed the most logical.
Have not issues with Rawtherapee, but I wanted to give this a shot.
Thanks for info
Dear dt-team thanks for your effort to develop dt for Windows! A happy new year and success for the following development steps!!!
Now my question: in my notebook I have two graphic 'systems":

Which one is active and used during dt, because all cl-module compilings are done for both?
Hi,
I found the answer by myself: GeForce is active! A tool on my notebook shows by GeForce supported programms and dt is listed when I have dt active.
Hi. I am using DT on windows 8.1 on a Lenovo Yoga 2 Pro. I am unable to activate OpenCL. Is there any way to activate that? Scrolling in Lighttable mode is very slow. Is there something I can do to improve performance?
Thanks in advance.
Please read first the FAQ at least:
Hi, I see there has not been much action on here for a while so not sure if this place is active anymore. Anyways just like to say that I have installed the new 2.4.1 for windows and can tell you that there has been a huge change to the export times I am getting when exporting TIFF. I was getting export times of around 5 minutes or more, now it is between 55 seconds to a minutes, so a huge difference. This is without OpenCL using my graphics card which I just can not seem to get to work properly.
If I edit the darktable.rc and change use CPU to true, OpenCL will pick up the CPU and GPU and it looks like it is working when using the opencl test command, but, when using Darktable in general it is really slow with it showing working for ages when I make changes. Probably some confusion between the CPU and GPU. Meh I am happy with the export difference the way it is without using OpenCL
So a huge thank you for the continued development of the great software
Cheers
Jason
Hi Jason, yes, the TIFF export slowness has been fixed, just I believe we forgot to mention in the release notes.
We have added additional debug information to OpenCL initialization. Would you mind running darktable-cltest and share the output?
It’s in the release notes, under “Dependencies”.
