Hi,
did some tests:
Intel® Core™ i5-2500 CPU @ 3.30GHz × 4
GeForce GTX 750 Ti, 2GB,128-bit
Ubuntu 15.10 64-Bit, 16GB
opencl - m1
[dev_process_export] pixel pipeline processing took 1,075 secs (2,872 CPU)
opencl - m3
[dev_process_export] pixel pipeline processing took 2,001 secs (6,548 CPU)
no-opencl - m1
[dev_process_export] pixel pipeline processing took 1,289 secs (3,892 CPU)
no-opencl - m3
[dev_process_export] pixel pipeline processing took 2,289 secs (7,528 CPU)
Details attached
With opencl activated darkroom mode is much more snappy.
If you need more information, let me know.
