There are a few issues with your settings (I’ll expand on this later as on the train on way to work now). But your low generation number isn’t to do with your settings.
I believe that you have made your window inactive or shut your screen off on laptop maybe? EA studio needs to run on an active browser.
Can I ask a few questions to help you get the most generated EAs for your setup.
1- What browser are you using? (Chrome is by far the best)
2-Are you running on a desktop or laptop
3-What computer processor does your computer have?
We can tackle the low generation number first and then once sorted will discuss some of the other parts of your settings 😉
