How to fix random walking (forced to slow walk / can’t sprint). After experiencing this myself I found many other players reporting the same problem online, but no information on how to fix it. I managed to fix it using ‘Anti Deadzone’ in Controller Configuration.
How to Fix Random Walking Bug
Open Steam Big Picture mode with the icon next to minimize
Depending on your controller, you may have to enable configuration by navigating to settings
Then select Controller Settings
Check the box to enable configuration for your controller
Select Dark Souls Remastered, then Manage Game, then Controller Configuration
Navigate to the Left Stick and select it
In the Additional Settings menu select Output Anti Deadzone
Move the slider to the right to adjust the yellow circle’s size. You may need more or less than is shown in this image
After that you may find it difficult to input a slow walk. To fix this, select Anti Deadzone Buffer under the previous Additional Settings menu.
Adjust the slider to show a smaller dark circle within the yellow circle. By adjusting these two settings you should be able to run consistently.
