Game Tuner 18.104.22.168 and Game Launcher 3.2.05.4 are NOT compatible
As you can see in attached screenshots, one supresses the other. The device in question is a tab s3 running oreo. The same is observed on a note 8 running oreo.
GAME TUNERGAME LAUNCHERThank you.
I asked at our end about this one for you. The development team have replied that Game Launcher includes Game Tuner's main functions, and have advised using Game Launcher without Game Tuner.
