Hi Christian,
thanks for the feedback. Your observation is inline with most others. In
general users see a slight go noticeable speed improvement by OpenCL in
Marketsteijn demosaic. So it seems reasonable to leave Markesteijn
OpenCL on by default.
Best wishes

Hi Ulrich,
sorry for the delay for testing (i not very concerned as i don't have
x-trans sensor ....
but as i'm reading result form ML i saw only nvidia card, so i have make
the test for you ... :
for me, it's nearly unusable wihout opencl (even with my 8 core), it's too
slow
But with the opencl is much better, and the perf say the same thing :
X4 faster & X20 less usage of CPU
