MY XSX is incredibly fast. Boot up from cold is about 6 seconds and from sleep is about 1 second. The menus and store are almost instant, which is a refreshing change from the X1X.
Assassin's Creed Valhalla running at 4K60 is as good as they say it is
Some glitches with games, but I think it's because all my mates have slow machines and my console is struggling to wait for them.
Love the new console
