I use the same on a 2015 Macbook and it's super slow. My computer runs hot while I have captivate open and Captivate is always listed as using signifiant amount of energy. I keep hoping for an update that helps. I almost wish I didn't update to the 2017 release right away.
I have used Articulate as well and it is a joy to use. the biggest difference is that it has never crashed on me. On the other hand, Captivate crashes regularly in every version ( I have used captivate since version 4). The only reason we are not using Articulate is that my office is Mac based and Articulate only runs on windows. If they ever develop a mac version, Captivate will be DEAD!
