Witcher is a mod for the game, you can download it for free and you don't need to pay for the app.

It removes the contour around objects and clues when you use the witcher senses. It's a very powerful mod, it will remove almost all the clutter from the screen, so it's really nice and easy to use.

It has many different options, it can be turned off and on, and you can also turn it off if you don't need it.

Although, the fisheye effect won't work with this mod enabled.
