By this, do you mean that the input doesn't fully reset by itself once released?
it takes a while to reset
I take it this is with Xbox controller mode?
yes
Are the attached images both with the new firmware/have you compared with the previous version?
they are both with the new firmware, I haven't been able to test with the previous version (will do so soon)
The max diagonal axis is kinda a property of how the xbox controller interface works, we provide a integer number, not a float. So it's the driver that interprets what the values represent here. Does it cause a problem for you?
it's just something I noticed while testing the input and might be the reason why I stop sprinting in some games when switching direction from front left to front right
