Hello,
I noticed quite a dramatic drop in performance between version 4.8.1 and 5.0.0 and now 5.0.1, especially when exporting jpegs. I recall that with version 4.8.1 OpenCL was available for my laptop and in use. It is not the case anymore and I cannot activate it.
I have an integrated GPU that may cause issues as stated in other posts here, but it was working in the past.
More about my setup :
-
My drivers are up to date, from intel directly and not from Windows
-
When running
darktable -d openclas stated in the manual I get :
12.0401 [opencl_init] opencl disabled via darktable preferences
But I cannot change the preferences in the menu :
Does someone have an idea of how to have OpenCL working again ?
Full Output of darktable-cltest.exe hidden to keep the post compact
