CFX ok in games but AB report GPU2 Usage 0% (flat line)

My crossfire is working properly in games with high FPS but Afterburner 4.1.0 reports GPU2 0% (flat line) in monitor window and in OSD in games.



I know CFX is working properly by CFX logo and 45 fps in Dark Souls II downsampled from 8K to 1080, Risen 3 at 5K to 1080 45 FPS also.



These numbers are not posible in a single 290X.



What could be wrong in my AB settings to don't log GPU 2 usage %?¿?
