Some FromSoftware Movement Deadzones
Unfortunately I couldn't sync the inputs well so a direct comparison isn't as clear as I'd like.
First clip section is demonstrating the shape of the deadzone, the second, the diagonal/cardinal movement right around the deadzone, third, movement within restricted ranges, fourth, diagonal movement outside of restricted range.
Dark Souls 3 uses the same deadzones as DS1 and Sekiro: https://i.imgur.com/GOMzkBl.png
looklook876 has tested Bloodborne, which are also the same: https://www.desmos.com/calculator/osx...
OBS Studio for recording game footage and Inputs.
TitanTwo GtunerIV Device Monitor for Stick Input
Davinci Resolve for Editing.
These are the Xbox versions of every title, but I believe the deadzones are the same between platforms.
