Disable Keyboard/gamepad detection box
Pertama masuk ke dalam tempat instal the wicther biasanya di programfiles C:
1.Go to your Witcher 3 folder location and go into this folder:
"...\The Witcher 3\bin\config\base"
2.Open up "hidden.ini" with notepad.
3.Change "LockControlScheme=0" to "LockControlScheme=2"
This will get rid of the annoying message box and will always show the controls for the controller. You still can switch to your KB/M whenever you want, but it won't display the KB/M controls on the hud.
