How to activate geforce ansel mode?

I have downloaded the latest nvidia geforce game ready driver and my KCD is updated to 1.3.4. My videocard is the GeForce 970, so it should be compatible. How do I activate the ansel feature of the GeFroce experience? When I press ALT+F2 nothing happens, there is no error message that it cannot be activated. However, when I start the game there is a notification of the general GeForce Experience Overlay.

Here is the menu. I’ve set logging to verbose, but I’m getting no logs :frowning:

Try 391.01! Works for me. With 391.24 Ansel doensn´t work (with KCD).
