Random control issue

I played this morning and it felt great.
A few short hours later I come back for some more Warzone action. Load in and take off running and immediately notice it feels like my controller has a 0.5 second input lag. My shots are literally everywhere. I mean I’m not barely missing, I’m missing by 10 feet or better. The game feels terrible and I can’t figure out what the issue is.
I’m using an elite and nothing has changed from this morning to this afternoon. Batteries were just changed last night.
Literally makes no sense and infuriates me.

I keep having to play with my acceleration and sensitivity settings. It feels different every time I pick up the controller. Maybe I’m just different every time, but that takes me down a philosophical road too complex to travel for an Xbox game, so I’m going to blame the game.
