I checked the VKBConfig tool and it is also there.
Can it be removed? Is it something added by default?
Best regards!
EDIT: I found the reason. By default the RotX axis was configured with a Deadzone of "15" (grades?) in the middle. I changed to "0" and now it's a continuous movement.

By the way, ,Incredible software the VKBDevConfig tool and incredible Hardware!!! Millions os customizations allowed!
