Slow grenade response

Hi
i have noticed that grenades throw about a second after I want them to but hit detection seems to be fine
xbox network stats are
75mbps down
18mbps up
0% pkt loss
MTU 1480
latencey 150ms (which is high because I’m in UK and it’s pinging a US server)

i have a wired connection as well

this is never happend on the xbox 360 and my other games (Destiny, Titanfall, CoD AW) work perfectly (and forza 5)
cheers
