Hi Guys,
I am experimenting on a new windows machine. Win 10 - DT 2.4.4
GPU Intel UHD Graphics 630 and NVIDIA Quadro P1000
I have read and tried
https://www.darktable.org/usermanual/en/darktable_and_opencl_multiple_devices.html
However - no matter what I do - it looks like DT *always* defaults and
heavily utilizes the Intel Graphics 630.
The result is - no benefit at all when using open CL. In fact - using
CPU is about 30% faster (if my tests were correct) than using Intel GPU.
Meanwhile Nvidia is present but does nothing. 1-5% utilization.
This "darktable -d opencl" does not do anything on windows - simply blank.
So I identified the cards with "darktable-cltest.exe"
Setting device preferences - I tried both with the name of the cards and
also by number - 0 or 1.
Sadly - regardless what I did - I was unable to force DT to use Nvidia.
Can anybody help with this please?
Regards,
B
