Nvidia AA & W10 Fall Creators Update

Sorry for the late reply I miss notification, btw you need to go on settings>games and disable everything related to Xbox and gamebar...
They just rearranged the menu and changed some names to make it difficult to us

 

Had similar issues when I upgraded my Nvidia driver. Lost all AA. Tried in-game setup, Nvidia inspector and Nvidia control panel. Nothing worked except switching to windowed mode. Tried the above suggestion and disabled full screen optimization. No success. What did work for me though is making sure all Nvidia settings were set to default and running AMS once as administrator. I then set AA through the AMS tool and unchecked windowed mode. Success. Worked like a charm. Hope this helps someone. Cheers.

 

I just deleted my Nvidia AMS profile and let the AMS configuration do the job
