Re: NVIDIA Ansel
I believe that you need to install Geforce Experience to have Ansel available. Ansel is a 3rd party app, and not actually part of MEA. If Ansel is running, when you start MEA, you should see a brief overlay in the top right corner of your screen that says: "hit Alt+Z to record your gameplay". In game, when you hit Alt+Z, you will get an overlay that will allow you to take screen shots or videos of you game.
