Hi all,
Just noticed something wickedly strange earlier today, for some reason
my exports are going way, waay faster than before so I wanted to get
some timings with 'darktable -d opencl' to see how much faster it is.
However, running that revealed I'm not even using OpenCL :| Somehow,
DarkTable 1.6.1 without OpenCL is a lot faster than 1.4 was with.
This is the error I'm getting:
ochal@BigMonster:~$ darktable -d opencl
