The Elite

Are you using the digital download? Seems like everybody complaining about menu lag and such are using the digital version.
My disc version has no lag with menus etc.
As for the online, I haven't tested it. I get too frustrated with online games, and the only time I ever tried it was on '13 on my Vita and it was too laggy. They supposedly fixed everything starting with last years '15 edition.
I am digital and my menu lag is gone. I only had it when the game just released and everyone was hitting the servers at once. It's fine for me now.
