we have had the same workstation since 2013 and had Solidwoks 2013 -14-15 and now 2016 and have not noticed much change in resources but bcp new features and improvements that really make life easier. On the other hand, if you still have the home license option, it will jump during the migration...
Thank you for the answer, what do you call the home license? There are several workstations in network license and one workstation in one-workstation license, is that it?
It seems to me that 2014 and the last version to have it. In fact there is the on-the-workstation license and you can activate a second Solisworks with the same license number for your home, hence the name home license but there have been abuses (the activation of the home license on a second workstation in a company) that's why they stopped.
