I used the the package for Suse (Enterprise) and opened/copied the files
with mc. I tested 16.60 and 17.10 to see if the OpenCL performance
differs (I read somewhere that 17.10 has OpenCL regressions). I used the
integrated benchmark of NeatImage v8.2 (there is a demo version) and got
around 15Mpix/sec for both. So, I stayed with (I think) 17.10.
I don't know, what the libGL errors mean...
Everything seems to work. (I ran the big zypper dup last night, so my TW
is up to date)
Cheers,
Michael
