Console aim needs to change
There's 2 different aiming in this game
Camera / ADS
There should probably be 3, with a Shoulder Aim....
But.... here's the problem, even when using the same deadzone & curvature, the Camera & ADS aren't on the same deadzone
More problems.... Adjusting literally everything effects deadzone, upping sense lowers deadzone & lowering sense highers it.
Changing curvature also changes deadzone quite drastically....
Diagonal aiming has different deadzone.... you have to pull 10% more for diagonal inputs....
And 0 deadzone isn't 0.... its like 15 minimum, depending on what other settings you have?.?.?.
I believe your game is uncalibrated to Circle anolog aiming, because when I play on a uncalibrated controller/Square analog it makes diagonal aiming 100x faster....
Try fix console aim, It can't get much worse.
