I just got my steam controller in, pretty happy with how fast it got here and etc however the default deadzone is just barely enough to stop the right stick from drifting upwards, if I put a literal feather weight of pressure on it, it immediately works to push upwards, which okay I'd expect from TMR sticks however it takes 5x as much pressure to move the stick in any other direction, so there's a centering bias straight out of the box.
Totally usable but there's seemingly no way to calibrate the stick centering and improve circularity, only increase the deadzone which yes will make the issue less pronounced but doesn't inherently improve the circularity.
Is this a common thing? I've not really bought a new controller in like 8 years 😂
