When using a high resolution monitor you could have many have problems
if you need Window scaling 150%. Menus can get corrupt like the
most used one modify dimension in parts and assemblies.
Another user has found problems even with 125% scaling since SW2014.
Some menu fonts are far too big and some far too small, also the vertical distance
between text in menus, trees and RMB can be far too big causing unnecessary
scrolling and mousemovements.
I posted several pictures of these problems
Selecting dimensions to edit in parts and assemblies doesn't work properly since
SW2014 when showing dimension flat to screen, it will cause many missclicks.
Performance is a bit better than SW2013 but worse than SW2012
Working very well here. The new Style spline and fillets make it an essential upgrade here. All our add ons are now 2014 ready ( Keyshot, Power Surfacing, T Splines, Maxwell) and Zygote works fine.
Some very useful changes to drawings and general interface. Speed is much the same as before 2012 and 2013. Stability as good as earlier versions. I have noticed that in some circumstances SolidWorks is flagging up out of resources errors even when there is plenty of RAM available. Apart from that, recommended.
