Input Latency

Ever since the update I have been dealing with occasional input latency. It gets really bad; almost half a second delay (think Halo 4 co-op). Lag is one thing, but this is intolerable. My controller is wired so I know it isn’t the issue. My internet speed isn’t phenomenal, but before the update the lag was hardly noticeable and now it’s like my controller is bouncing off the moon. Anyone else experiencing this? Anything I can do to possibly fix it (other than get faster internet)?
