With the Nightmares & Visions update, we've resolved an issue with the deadzone setting under the 'Controller' tab in 'Settings'. Now, when your deadzone is set to 0, it will actually apply as 0, meaning any stick drift will be noticeable. In the past, the correct value was not being applied.
Those that have lowered their deadzone previously are at risk of experiencing this issue.
You should be able to resolve this by simply increasing the deadzone - we recommend starting at 0.05 and slowly increasing the value should the issue persist.
