Hi Rob and the darktable team,
In your exemple, we see a speed factor of nearly 10 times
And Cpu consume in factor 25
So the GPU is a realy very good usage in darktable.
But, i see small "issue" on your exemple or your performance ! :
[pixelpipe_process] [export] using device 0
[dev_pixelpipe] took 0.076 secs (0.250 CPU) processed `highlight
reconstruction ' on CPU, blended on CPU [export]
[dev_pixelpipe] took 0.260 secs (0.902 CPU) processed `output color
profile' on CPU, blended on CPU [export]
[dev_pixelpipe] took 0.037 secs (0.041 CPU) processed `gamma' on CPU,
blended on CPU [export]
[pixelpipe_process] [export] using device -1
[dev_pixelpipe] took 0.065 secs (0.235 CPU) processed `highlight
reconstruction ' on CPU, blended on CPU [export]
[dev_pixelpipe] took 0.260 secs (0.900 CPU) processed `output color
profile' on CPU, blended on CPU [export]
[dev_pixelpipe] took 0.013 secs (0.038 CPU) processed `gamma' on CPU,
blended on CPU [export]
So 3 modules doesn't use the GPU (or failed to use it ? ). It's normal ?
it's not (yet) implemented ?
And on gamma module is 3 time slower (with equel cpu usage), strange ?
Regards
