Yes it still works using the same thing I posted from last night. You need to be sure to run steam in admin startup. One thing to note im plugged in using the usb cable and of course the button layout is a xbox pad in game so you need to get accustom to that.
Start steam in admin
Add madden to steam
Enable ps4 and xbox controller support (check them in big pic mode settings)
Be sure origin is closed
Run madden from steam big pic mode origin starts at that point
When the game loads in the ds4 should be a xbox pad
I have been using this method for 2 days now with no issue running windows 10
