everytime i press ESC during benchmark i'm getting an error message. By turning NVIDA Shadowplay On and Off i've found that Shadowplay was the problem. Here's a picture of the error message. I'm not if this error is caused by Catzilla or ShadowPlay. In other games ShadowPlay is working fine for me. I'm using the current Geforce Experience 2.0 (beta version) but i think i already had the same bug with previous versions.
