just play BF1 and have a freesync pro/2 monitor, then i found if i used the AMD optimized which is default, the game isn't playing smoothly and in freesync way, but when i switch it on manually, the game is running better , smoothly and actually, in freesync. so i guess AMD optimized isn't working for freesync monitor or its set option is off generally i guess . but some game work like this is better , some didn't needed, like BFV( which trully in freesync )
