I put my aim acceleration to 10; apparently that turns it off and you limit the jerkiness of your aim changing speeds randomly.
I have much smoother aim movement as a result.
I read that too, but then I saw something about 0 being the best setting for aim acceleration. I believe 10 makes it so you always aim at full speed.
I can't remember my exact settings, but I know my deadzone and aim acceleration are set to 0. I think my targeting's 8 or 9, and scoping sensitivity is like a 7 or 8.
Anyone else playing with controller type B? It let's you hold LT to go into ADS.
