Reticle/Sensitivity Issue (Halo 5)

When playing Halo 5 (single and multiplayer) The reticle onscreen gets a shutter effect(flickers) and drifts when you are aiming. While this is happening the sensitivity is atrocious. It feels like playing in molasses. There is a noticeable delay when you hit the stick one direction and stop. It is similar to a movie where the audio falls out of sync by a half second, it feels the same as the old Mario games on the ice levels where you have to compensate for the “ice slip” It is disorienting and makes halo 5 basically impossible to play. The effect is constant and does not go away.

I have uninstalled and reinstalled(digitally). Have tried using a friends hard copy. Nothing seems to be working. Other games work perfectly fine and do not have this issue, and the xbox itself works perfectly fine. Internet speed is not an issue. Nobody seems to have this problem that I can find. I am at a complete and utter loss.
