minimum hw specs to run fps sample?

Hello, I am trying to run the FPS sample on a 2014 i5 mac mini with 8GB of memory (and running windows 7). After building the game I am starting the headless server with two clients and it partially loads and then fails for various reasons. Sometimes I get to the point of one of the clients showing the game lobby In task manager I see memory is maxed out. My FPS shows as 3 or 4.

So.... looks like a 2014 mac mini with 8GB can't do it. What are recommended minimum specs to successfully run this FPS sample game with enough head room for further development in this sample? I am not finding too much info on this, a pointer would be great.

Thank you for any help.
