Update of actions I’ve done based on yall inputs:
- forced priority to use one device at a time, but it still tried to use the others.
- changes nvidia drivers from game ready to studio
- delete the kernels in the cache to regenerate them
- changed the memory headroom to 800 per OpenCL analysis... Darktable... much faster with Opencl disabled...something wrong?? - #22 by kofa
and other settings from that thread - checked performance with and without OpenCL
In summary, the only way to avoid the black image is by disabling the OpenCL or the Haze Removal. It seems that the Nvidia card is not being used in most modules with the opencl. The system switches to CPU, so there is not a big performance improvement. I sure would like the system to take advantage of the 12gb fast card.
