I have used Rawtherapee and Darktable on an infrequent basis for the past 8 months but mostly Rawtherapee. I was starting to switch over to Darktable to gain the database features and decided to go through some more youtube tutorials but noticed that now it takes considerable amount of time to open a .RAF file (20 seconds) vs .NEF file. Of course if I zoom into the image, I get the “working” message and another 20 second wait. I have no idea what has changed in Darktable or Windows 10 but Darktable is not usable due to the long delays. I tried uninstalling and reinstalling darktable but no difference. Demosaic is set to the default. Does anyone have any ideas what I can check to resolve this issue? Rawtherapee works just as before with no delays opening .RAF files. Thanks in advance!!
Windows 10 22H2, up to date.

Yes, opencl is on. I need some help with your second request. “post a darktable -d perf”… Is this run darktable with argument “-d perf”? If so, I tried this and darktable started but where do I find the results?
I agree that a nvidia 1050 is no where near the latest gen but this video card worked fine a couple of months ago. Unless it is having issues… No issues with other software. (Rawtherapee, DaVinci Resolve, etc)
What setting you have on that module with the raf file? I’m not at the PC, so I can’t see your setting/xmp right now.
Your card is 2gb, but we reserve 0.4 as headroom for other OS functions and then you selected default for memory, so it uses 70% of that. Change to large so it could use 90%. Maybe this makes larger tiles (faster processing).
There is another option using a new feature that I haven’t used. It is explained in the manual: j. advantage hint
I tried to force my system to not have enough memory (via a internal parameter). It creates the tiles but I’m not near 20s for that module using your module settings. My card is a 3060, so it has more processing units.
Last thing to try. Go to the folder that has the log file. In there you will see some folders with the words kernel (maybe they include the word nvidia). Go ahead and delete them. When darktable starts, it will generate (compile) new ones using the nvidia drivers.
I deleted the folders, restarted DT, opened the same file and no change in time to open. Sorry for the late reply. The message board wouldn’t let me post the message. Too many for a new user. I have to wait 15 hours. LOL
