We didn't start using SW2013 because of performance problems
and corrupted font problems because of Windows scaling. I hope
SW2014 will do better.

I will test SW2012 against 2014 in the near future but I wonder if anybody
already tested with large assemblies and section drawings. I am especially
interested in rebuilding times of both against SW 2012. Also responsiveness
is of interest.
