I recently bought a tobii eye tracker 5 and started playing the game again, but quickly noticed a strange and annoying issue where my bullets were always firing lower then the reticule when aiming down the sights.

Thankfully I found this topic from the old forums back in 2019, where other users had the same issue and found it was due to the tobii eye tracker support in the game, specifically the "Extended View Aim" option. Turning that off will stop the issue from happening while still allowing you to use eye tracking in the game.
Hopefully this helps anyone else who may encounter the issue in the future, though it would be nice if Ubisoft looked into it though as it's been two years already I'm not holding my breath.
