Gameplay captured

[1v0live]

I noticed by accident some gameplay videos of KCD in my videos folder, where even the microphone is on. Is this a combination of keys i am unaware of?
In the details of the video files i could see it was encoded by "NVIDIA App" but i never signed up to have my gameplay captured. Also, it is the only game captured.

It is a new feature of NVIDIA software. It will capture highlighted moments from your gameplay (often cinematics and combat).
You had to agree with it when installing KCD. It can be disabled in the NVIDIA settings.
