WOFF's AA in the Nvidia Control Panel is " override " ...
I updated Windows, i uninstalled Avira antivirus, i disabled a lot of services i dont need, uninstalled CFS 3, but nothing changed.
Its very hard to find the culprit.Nearly impossible.It could be the Saitek X55 Rhino software
It could be the Logitech drivers ( Mouse G502, keyboard G510S )
Anyway, i'll keep searching.
Thank you very much for helping me.
