Halo 5 Latency Issues after Hammerstorm Update

Hello guys,

I have a decent internet connection . I ping 15-40ms to google. and enjoy all xbox live games . I was enjoying halo 5 fully but after this hammerstorm update . every play list says ONE OR MORE PARTY MEMBERS has LATENCY ISSUES . RED EXCLAMATION.
and the game feels laggy.

anyone else feel the same?
its definitely not my internet.
Im on DMZ IP too.
