Technically, some games don't work which is what DS4 fixes. 
Also games on game pass don't work unless you have DS4.

If you don't mind paying 4 bucks - DSX on Steam is a super good tool to emulate any kind of controllers. It beats DS4 in my opinion.

All you have to do is install it once through steam and the rest is automatic.
